Procedure

A solution of (5-bromo-2-chloro-pyrimidin-4-yl)-(S)-piperidin-3-yl-amine (3.5 g, 12.2 mmol) and diisopropylamine (6 g, 46 mmol) in dichloromethane was cooled to 5° C. and treated with methansulfonyl chloride (2.1 g, 18 mmole). After stirring at 20° C. for 2 hours, the reaction was concentrated purified by silica gel chromatography to give 3.1 g (43% from step 1) of (5-Bromo-2-chloro-pyrimidin-4-yl)-((S)-3-methanesulfonyl-cyclohexyl)-amine.
