Reaction Steps

A solution of potassium cyanate (53 mg) in water (1.5 mL) was added to a solution of (R)-5-cyano-N-(3,4-dimethoxybenzyl)-2-(3-pyrrolidinylamino)benzamide (100 mg) in acetic acid (1.5 mL). The mixture was stirred for 3 hours at 60° C. and then for 2 hours at 90° C. The reaction mixture was concentrated in vacuo and the residue was partitioned between chloroform and an aqueous saturated sodium bicarbonate solution. The organic layer was dried over magnesium sulfate and concentrated in vacuo. The residue was purified by thin layer chromatography developed with 5% methanol in chloroform. The obtained product was triturated with diethyl ether to give (R)-2-(1-carbamoylpyrrolidin-3-ylamino)-5-cyano-N-(3,4-dimethoxybenzyl)benzamide (22 mg) as a powders.
