Procedure

18.05 g (90 mmol) of 4-chloro-2-methylsulfonyl-6,7-dihydro-5H-cyclopentapyrimidine were dissolved in 200 ml of methanol. At 45° C., 16.7 g of sodium methoxide (as 30% strength solutions in methanol) were added dropwise, and the mixture was stirred for 2 hours. The solution was evaporated, taken up in ethyl acetate and acidified with dilute hydrochloric acid, and the ethyl acetate extract was evaporated. 15.5 g of an oil remained.
