Procedure

To a mixture of ethyl (2E)-3-(6-{(tert-butoxycarbonyl)[(3R)-3-pyrrolidinyl]amino}-3-pyridyl)acrylate dihydrochloride (110 mg), 4-(chloromethyl)-2-phenyl-1,3-thiazole (53.1 mg), and DMF (2.5 mL) was added K2CO3 (123 mg). After stirring for 2 hours at 60° C., the reaction mixture was partitioned between ethyl acetate and water. The organic layer was washed with brine, dried over MgSO4, filtered, and evaporated in vacuo to give ethyl (2E)-3-[6-((tert-butoxycarbonyl){(3R)-1-[(2-phenyl-1,3-thiazol-4-yl)methyl]-3-pyrrolidinyl}amino)-3-pyridyl]acrylate (133 mg).
