Procedure
To a suspension of 2-(1H-indol-4-yl)-4-morpholin-4-yl-thieno[3,2-d]pyrimidine-6-carbaldehyde (54 mg) in anhydrous methanol (8 ml) was added phosphorus sulphone (34 mg), followed by sodium methoxide (148u1). The reaction mixture was stirred at room temperature for 4.5 hours, then evaporated onto silica and purified by flash chromatography to give 2-(1H-indol-4-yl)-6-((E)-2-methanesulfonyl-vinyl))-4-morpholin-4-yl-thieno[3,2-d]pyrimidine (30 mg).
