Methanesulfonyl chloride → HCID 86615300, compound

Participants

Reaction Steps

To a stirred solution of 4-(5-hydroxy-pyrimidin-2-ylamino)-piperidine-1-carboxylic acid tert-butyl ester (0.74 g, 2.5 mmol, 1.0 equiv) in dichloromethane (20 mL) were added N-ethyl diisopropylamine (1.09 mL, 0.82 g, 6.3 mmol, 2.5 equiv), followed by methanesulfonyl chloride (0.24 mL, 0.35 g, 3.0 mmol, 1.2 equiv). After stirring for 4 h, the reaction mixture was poured into ice water and extracted twice with dichloromethane. The combined organic layers were washed with water, then dried over MgSO4, filtered and concentrated by evaporation under reduced pressure. The crude product was purified by column chromatography on silica eluting with a gradient of dichloromethane/methanol to give 0.87 g (93%) of the title compound as colorless foam. MS (ISP): 373.1 [M+H]+.
