Abstract
A process is described for the production of 2-isopropyl-4-methyl-6-hydroxypyrimidine (oxypyrimidine) by reacting isopropylamidine in an alkaline lower alkanol solvent system with an alkyl acetoacetate to close the ring and form the oxypyrimidine in a continuous flow multi-stage reactor (MSR) under controlled multi-stage conditions whereby the reactants contact each other in each of said stages under conditions which reduce the possibility of the formation of unwanted reaction products from said reactants in said solvent system.
