Procedure

To a solution of (2E)-3-(6-{[(3R)-1-phenyl-3-pyrrolidinyl]amino}-3-pyridinyl)acrylic acid hydrochloride (37 mg), O-tetrahydro-2H-pyran-2-ylhydroxylamine (19 mg), and 1-hydroxybenzotriazole (22 mg) in N,N-dimethylformamide (1 mL) was added 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide (25 mg) at 4° C. The mixture was warmed to ambient temperature and stirred for 8 hours. The reaction mixture was added saturated NaHCO3 (1 mL) and water (4 mL). A resulting precipitate was collected by filtration, and washed with water to give (2E)-3-(6-{([(3R)-1-phenyl-3-pyrrolidinyl]amino}-3-pyridinyl)-N-(tetrahydro-2H-pyran-2-yloxy)acrylamide (43 mg).
