Procedure

A mixture of 5-(2-(methylthio)pyrimidin-4-yl)thiophene-2-carboxylic acid (200 mg, 0.79 mmol), morpholine (69 mg, 0.79 mmol), EDCI (182 mg, 0.95 mmol), HOAt (21 mg, 0.16 mmol) and triethylamine (159 mg, 1.58 mmol) in dichloromethane (20 mL) was stirred at rt for 24 h. Water (50 mL) was added and the mixture was extracted with dichloromethane (3×50 mL). The combined organic layers were washed with brine (100 mL), dried over anhydrous sodium sulfate and filtered. The solvent was removed in vacuo and the residue purified by flash chromatography eluting with ethyl acetate/hexane (1:1) to give the intermediate (5-(2-(methylthio)pyrimidin-4-yl)thiophen-2-yl)(morpholino)methanone as a white solid (200 mg, 78%). MS (M+H)+ 322.
