Participants

Conditions

Temperature: 35 °C

Procedure

56 ml. (0.4 moles) of triethylamine are added to a suspension of 42 g. (0.2 moles) of 6-APA in 600 ml. of methylene chloride. Subsequently 430 g. (0.4 moles, 50 ml.) of trimethyl chlorosilane are added to the obtained solution at 10° C., and the mixture is stirred for 60 minutes. Thereafter the mixture is heated to 35° C., 104 g. (0.2 moles) of phenylmalonic acid phenylester pnetachlorophenyl ester are added, and subsequently 28 ml. (0.2 moles) of triethylamine are introduced dropwise into the mixture. The reaction mixture is stirred at room temperature for 3 hours, thereafter it is neutralized to pH=7 with 200 ml. of 8% aqueous sodium bicarbonate solution.

Workup
