Procedure

To a solution of 2-(tetrahydropyran-4-ylamino)-6-(2-fluorobenzoyl)thieno[2,3-d]pyrimidine (300 mg) in ethanol (30 mL) was added sodium borohydride (0.4 g) at room temperature and stirred overnight. Ethyl acetate (50 mL) was added to the reaction mixture. The organic layer was separated, washed with brine, dried, and evaporated. Purification by preparative TLC (silica gel, 50% EtOAc/hexanes) gave 140 mg of the alcohol. MS: 360.2 (M+H).
