Procedure

2.10 g (3.55 mmol) of ethyl 4-({2-[4-(5-chloro-2-cyanophenyl)-5-methoxy-2-oxopyridin-1(2H)-yl]-3-(cis-4-methoxycyclohexyl)propanoyl}amino)benzoate (racemate) in 129 ml of ethanol/water (2.6/1) were reacted with 5.89 g (18.1 mmol) of caesium carbonate according to General Method 4. After complete conversion, the pH was adjusted to 5-6 with hydrochloric acid (1N) and the mixture was stirred for another 30 min. The precipitate was filtered off with suction, washed with a little water and dried under high vacuum and it corresponded to the title compound. Yield: 1.24 g (60% of theory)
