Procedure
To 6-chloro-nicotinoyl chloride (0.540 g, 3.07 mmoles) in dichloromethane (10 mL) was added of morpholine, (0.294 g, 1.1 equivalents) followed by triethylamine (940 uL, 2.2 equivalents). The reaction was stirred overnight at room temperature to give (6-chloro-pyridin-3-yl)-morpholin-4-yl-methanone. No starting material, 6-Chloro-nicotinoyl chloride, remained and mass spectrometry showed correct M+ ion. An aqueous work-up was performed and the crude material was taken to the next step. The crude residue, (6-chloro-pyridin-3-yl)-morpholin-4-yl-methanone, weighed 0.610 g (88% yield) after aqueous work-up.
