Morpholine → Morpholine-4-carboxamide

Participants

Reaction Steps

A solution of 315 mg of 2-chloroisonicotinic acid and 209 mg of morpholine in EtOAc (4.0 mL) was stirred as 1.27 g of a 50% solution of 1-propanephosphonic acid cyclic anhydride was added. This mixture was stirred at room temperature for six hrs. and another 1.27 g of the anhydride was added followed by stirring for another 18 hrs. The reaction was poured into saturated sodium bicarbonate solution and extracted with EtOAc (3×). The organic layers were dried over sodium sulfate, filtered, and concentrated to provide the morpholine amide.
