Reaction Steps
A mixture of 2-(3,4-dichloro-phenyl)-3-(3,3-difluoro-cyclopentyl)-propionic acid methyl ester (75 mg, 0.22 mmol) and 2-aminothiazole (27 mg, 0.26 mmol) in a solution of magnesium methoxide in methanol (7.4 wt. % , 0.63 mL, 0.44 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-(3,3-difluoro-cyclopentyl)-N-thiazol-2-yl-propionamide (44.2 mg, 49%) as an off-white solid: mp 154-156° C.; FAB-HRMS m/e calcd for C17H16F2Cl2N2OS (M+H)3 405.0402. found 405.0404.
