Reaction Steps

A solution of 2-[2-(4-chloro-phenyl)-3-cyclopentyl-propionylamino]-thiazole-4-carboxylic acid methyl ester (prepared as in Example 32, 127.7 mg, 0.31 mmol) in tetrahydrofuran (0.4 mL) was added to a slurry of lithium aluminum hydride (15.0 mg, 0.39 mmol) in tetrahydrofuran (2.24 mL) at 0° C. The reaction mixture was stirred at 0° C. for 2 h. The reaction was then quenched by the dropwise addition of water. The reaction was then diluted with more water (25 mL) and extracted with ethyl acetate (3×25 mL). The combined organic layers were dried over sodium sulfate, filtered and concentrated in vacuo. Flash chromatography (Merck Silica gel 60, 230-400 mesh, 75/25 hexanes/ethyl acetate) afforded 2-(4-chloro-phenyl)-3-cyclopentyl-N-(5-hydroxymethyl-thiazol-2-yl)-propionamide (63.4 mg, 55.4%) as a white solid: mp 115-117° C.; EI-HRMS m/e calcd for C18H21ClN2O2S (M+) 364.1012, found 364.1004.
