Procedure

To a suspension of 2-chloro-4-morpholin-4-yl-thieno[3,2-d]pyrimidine-6-carbaldehyde (500 mg) in methanol (20 mL) at 0° C. was added sodium borohydride (66 mg). The reaction was stirred for 2 h then quenched with 1:1 saturated aqueous sodium hydrogencarbonate solution—water (20 mL). The mixture was stirred for 10 min and then filtered, washed with water and air dried to give (2-chloro-4-morpholin-4-yl-thieno[3,2-d]pyrimidin-6-yl)-methanol as a white solid (489 mg).
