To a solution of 4-(2-chloro-4-morpholin-4-yl-thieno[3,2-d]pyrimidin-6-yl)-4-hydroxy-piperidine-1-carboxylic acid tert-butyl ester (335 mg) in DMF (3 ml) was added sodium hydride (60% w/w suspension in mineral oil, 41 mg) at 0° C. After 30 min, iodomethane (56 ul) was added and the reaction mixture was warmed slowly to room temperature overnight. Ethyl acetate/brine extraction and purification on silica afforded 4-(2-chloro-4-morpholin-4-yl-thieno[3,2-d]pyrimidin-6-yl)-4-methoxy-piperidine-1-carboxylic acid tert-butyl ester (219 mg).
