Procedure

To a solution of (1RS,2RS)-2-amino-1-(2-phenyl-1,3-thiazol-4-yl)-3-[3-(1,1,2,2-tetrafluoroethoxy)phenyl]-1-propanol (310 mg, 0.73 mmol) in acetonitrile (10 ml) were added 6,7-dihydro-5H-benzo[a]cycloheptene-1-carboxylic acid (132 mg, 0.70 mmol) and 1-hydroxybenzotriazole monohydrate (112 mg, 0.73 mmol), and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (140 mg, 0.73 mmol) was finally added. The mixture was stirred at room temperature for 3 days. The mixture was diluted with ethyl acetate, washed with saturated aqueous sodium hydrogen carbonate solution, water and saturated brine, dried over anhydrous magnesium sulfate, filtered and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane:ethyl acetate=5:1, 2:1) and recrystallization (hexane-ethyl acetate) to give N-{(1RS,2RS)-2-hydroxy-2-(2-phenyl-1,3-thiazol-4-yl)-1-[3-(1,1,2,2-tetrafluoroethoxy)benzyl]ethyl}-6,7-dihydro-5H-benzo[a]cycloheptene-1-carboxamide (247 mg, 59%) as colorless crystals.
