权利人:IHARA CHEMICAL IND CO
摘要:A process for the preparation, of (pyrimidin-2-yl)methyl ketones of the general formula (I), n nin which R 1 is in each case a C 1-10 -alkyl group, a C 3-8 -cycloalkyl group, an allyl group or an aryl-C 1-4 -alkyl group, and R 2 is a C 1-10 -alkyl group or aryl group. For this, a malondiimidate of the general formula (II),n n nin which R 1 has the meaning given above, is reacted with a β-keto ester of the general formula (III),n n nin which R 2 has the meaning given above, and R 3 is a C 1-10 -alkyl group. The compounds which can be prepared according to the invention are intermediates for the synthesis of agrochemical active ingredients.
