Disclosed is a 4-step process for the preparation of alkyl esters of 1-methylcyclopropanecarboxylic acid which comprises the steps of (1) converting &ggr;-butyrolactone to &agr;-methyl-&ggr;-butyrolactone; (2) converting the &agr;-methyl-&ggr;-butyrolactone from step (1) to an alkyl 4-halo-2-methylbutyrate; (3) producing a xylene solution of the alkyl 4-halo-2-methylbutyrate; and (4) contacting the xylene solution of an alkyl 4-halo-2-methylbutyrate from step (3) with an alkali metal alkoxide under conditions of temperature and pressure which causes vaporization of (i) an alkanol as it is formed and (ii) an alkyl 1-methylcyclopropanecarboxylate as it is formed from the alkyl 4-halo-2-methylbutyrate. Also disclosed are processes whereby the alkyl 1-methylcyclopropanecarboxylate, prepared as described above, is converted to 1-methylcyclopropylamine.
