Procedure

To a suspension of 2-chloro-4-morpholin-4-yl-thieno[3,2-d]pyrimidine-6-carbaldehyde (3.2 g, 11.31 mmol) in anhydrous THF (100 mL) and IMS (70 mL) was added sodium borohydride (0.47 g, 12.42 mmol) and the resulting mixture stirred at RT for 2 h. The reaction mixture was partitioned between DCM and a saturated aqueous solution of NaHCO3. The organic layer was isolated, dried (MgSO4) and concentrated in vacuo. The resultant residue was triturated with water to give the title compound as a white solid (2.9 g, 91%).
