A solution of 2-(4-methanesulfonyl-phenyl)-3-(tetrahydro-pyran-2-yl)-propionic acid (60 mg, 0.19 mmol), benzotriazol-1-yloxy-tris(dimethylamino)phosphonium hexafluoro-phosphate (127 mg, 0.29 mmol), and 2-aminothiazole (28 mg, 0.29 mmol) in methylene chloride (5 mL) at 25° C. was treated with triethylamine (0.08 mL, 0.58 mmol). The resulting reaction mixture was stirred at 25° C. for 16 h. The reaction mixture was then diluted with water (10 mL) and extracted with methylene chloride 3×15 mL). The combined organic layers were sequentially washed with water (1×10 mL), a 1N aqueous sodium hydroxide solution (1×10 mL), a 1N aqueous hydrochloric acid solution (1×10 mL), and a saturated sodium chloride solution (1×10 mL). The organic layer was dried over sodium sulfate, filtered, and concentrated in vacuo. Biotage chromatography (FLASH 12M, Silica, 20/80 hexanes/ethyl acetate) afforded 2-(4-methanesulfonyl-phenyl)-3-(tetrahydro-pyran-2-yl)-N-thiazol-2-yl-propionamide (54 mg, 71%) as a colorless oil: EI-HRMS m/e calcd for C18H22N2O4S2 (M+) 394.1021. found 394.1021.
