Reaction Steps

A mixture of 2-(3-chloro-phenyl)-3-cyclopentyl-propionic acid methyl ester (113 mg, 0.42 mmol) and 2-aminothiazole (84 mg, 0.84 mmol) in a solution of magnesium methoxide in methanol (7.4 wt %, 2.4 mL, 1.69 mmol) was heated under reflux at 100° C. for 20 h. The reaction mixture was then concentrated in vacuo. Flash chromatography (Merck Silica gel 60, 230-400 mesh, 80/20 hexanes/ethyl acetate) afforded 2-(3-chloro-phenyl)-3-cyclopentyl-N-thiazol-2-yl-propionamide (87 mg, 53%) as a white solid: mp 138.8-141.2° C.; EI-HRMS m/e calcd for C17H19ClN2OS (M+) 334.0906, found 334.0907.
