A mixture of 2-(3,4-dichloro-phenyl)-3-(3-fluoro-cyclopentyl)-propionic acid methyl ester (70 mg, 0.24 mmol) and 2-aminothiazole (26.3 mg, 0.26 mmol) in a solution of magnesium methoxide in methanol (7.4 wt. %, 0.63 mL, 0.43 mmol) was heated to 110° C. for 18 h. At this time, the reaction mixture was cooled to 25° C. and then concentrated in vacuo. Flash chromatography (Merck Silica gel 60, 230–400 mesh, 70/30 hexanes/ethyl acetate) afforded 2-(3,4-dichloro-phenyl)-3-(3-fluoro-cyclopentyl)-N-thiazol-2-yl-propionamide (2.3 mg, 2.7%) as a light yellow oil: EI-HRMS m/e calcd for C17H17Cl2N2OS (M+H)+ 387.0496, found 387.0499.
