Participants

Reaction Steps

70 g (0.235 mol) of 4-(5-chloro-6-ethylpyrimidin-4-ylamino) cyclohexanone ethylene ketal (starting material for Example C) were stirred at 50° C. for 8 hours in a mixture of 250 ml of tetrahydrofuran and 250 ml of 2N hydrochloric acid. For work-up, the mixture was diluted with 250 ml of toluene, and the organic phase was extracted by stirring with sodium carbonate solution and water. Stripping off the solvent mixture gave 53.4 g (90% of theory) of product, which can be reacted without further purification.
