Procedure

910 mg (purity 57%, 1.96 mmol) of 4-chloro-2-(5-chloro-2-oxo-1,2-dihydropyridin-4-yl)benzonitrile and 1.5 eq. of 2-bromopropanoic acid (racemate) were reacted according to General Method 4A, initially at RT for 2.5 h and then at 45° C. overnight. The desired product was obtained by precipitation with hydrochloric acid. Yield: 1.06 g (purity 78%, quant.)
