Reference Example 11 : 3-(Pyridin-3′-carbonylamino)tetrahydropyridin-2- one:; Oxalyl chloride (20 mmol) was added to a solution of nicotinic acid (10 mmol) in DCM (40 mL), along with one drop of catalytic DMF. The reaction mixture was stirred for 16 h and then the solvent was removed under high vacuum. The resulting crystals were dissolved in DCM (10 mL). In a separate flask, 3- aminotetrahydropyridin-2-one hydrochloride (10 mmol) and 2C03 (30 mmol) were added to water (30 mL) and stirred, giving a solution to which the acid chloride solution was added. The reaction was worked-up as above to give the product (0.10 g, 5percent):Vmax cm”‘ 3257 (N-H, amide), 1642, 1541 (secondary CONH, lactam, NH), 1591 , 1479 (aromatic pyridine ring).
