Reaction Steps

tert-Butyl[(1R,2R)-2-({[4-(6-bromopyrazolo[1,5-a]pyrimidin-3-yl)-5-ethylthiophen-2-yl]carbonyl}amino)-3,3-difluorocyclohexyl]carbamate (0.151 g, 0.258 mmol) was dissolved in methanol (1.29 mL) and KOH (14.5 mg, 0.258 mmol) was added. The reaction was heated to 65° C. until conversion to the alcohol was complete. The reaction was then concentrated under reduced pressure. The remaining residue was mixed with dichloromethane, washed with saturated ammonium chloride (aq) twice and brine once. The organic layer was mixed with water and extracted 3× with dichloromethane. The combined organic layers were dried with sodium sulfate, filtered, and concentrated under reduced pressure to give the title compound (0.100 g, 0.192 mmol). LRMS (APCI) calc'd for (C24H29F2N5O4S) [M+H]+, 522.2. found 522.0.
