Procedure

N,N-Dimethylformamide (1 mL) was slowly added to a solution of oxalyl chloride (0.13 g, 1 mmol) in chloroform (5 mL). 6-Morpholinonicotinic acid (0.21 g, 1 mmol) was added and the reaction mixture was stirred for 15 minutes. The reaction mixture was concentrated under vacuum, diluted with toluene and then concentrated under vacuum to provide 6-morpholinonicotinoyl chloride. This material was kept under vacuum at ambient temperature overnight and then used in the next step.
