A method for manufacturing an isocyanate compound represented by formula (2) (2) wherein R1 represents a methyl group, an ethyl group, a cyclopropyl group, a chlorine atom, a bromine atom, or a methoxy group; and R2 represents an alkyl group having 1 to 6 carbon atoms, comprising reacting an aniline compound represented by formula (1) (1) wherein R1 and R2 are defined as above with a phosgene compound at a temperature of from 40&#xb0; C. to the boiling point of the inert solvent in at least one kind of inert solvent.

Manufacturing method for an aromatic isocyanate compound

The present invention relates to a method for producing 2-[4-(4-chlorophenoxy)-2-(trifluoromethyl)phenyl]-1-(1,2,4-triazol-1-yl)propan-2-ol in high purity. Especially it relates to a method in which this compound is effectively separated from its 1,2,4-triazol-4-yl isomer.

Method for producing 2-[4-(4-chlorophenoxy)-2-(trifluoromethyl)phenyl]-1-(1,2,4-triazol-1-yl)propan-2-ol

The invention pertains to processes to produce dry biomass of pyripyropene producer organisms, processes to obtain pyripyropenes from such dry biomass, as well as to processes to produce compounds of Formula III and/or Formula IV and/or Formula V from the pyripyropenes obtained from the dry biomass. The invention does further pertain to the dry biomass itself, as well as processes using said dry biomass to obtain pyripyropenes for the production of compounds of Formula III and/or Formula IV and/or Formula V, including processes using said dry biomass to obtain pyripyropenes or compounds of Formula III and/or Formula IV and/or Formula V in order to produce pest control compositions, in particular insecticides, comprising such compounds.

Production of pyripyropenes from dry biomass

The present invention relates to a process for providing substituted phenyl ketones. Furthermore, the invention relates to the use of substituted phenoxyphenyl ketones obtained by the inventive process for the preparation of triazoles.

Process for the preparation of substituted phenyl ketones

The present invention relates to a process for the preparation of oxirane compounds of formula II from keto compounds III using dimethyl sulfide (CH)S and dimethylsulfate (CH)SO, forming the reagent IV, trimethylsulfonium methylsulfate [(CH)SCHSO], in aqueous solution in the presence of potassium hydroxide (KOH).

Process for the preparation of substituted oxiranes and triazoles

The present invention relates to a method for preparing the pyripyropene compound of the formula (I) which method comprises the following steps: i) subjecting a pyripyropene compound of formula Pyripyropene A to an alkaline hydrolysis to yield a 1,7,11 -trideacetylpyripyropene A, ii) reacting 1,7,11-trideacetylpyripyropene A obtained in step i) with cyclopropane carbonyl chloride to yield a raw product containing the pyripyropene compound of formula (I); iii) subjecting the raw product of step ii) to crystallization to yield a crystalline pyripyropene compound of formula (I) and a mother liquor; and iv) recycling the mother liquor or a pyripyropene compound containing fraction thereof to the alkaline hydrolysis of step i). 

Method for preparing a pyripyropene compound

In a continuous process for the preparation of alkyl nitrites and dinitrites, an alkanol or dialkanol is first mixed with an aqueous mineral acid, the reaction mixture obtained is then reacted with an inorganic nitrite and the product obtained can then be isolated immediately.
