実験手順

To a solution of 1 g (3.23 mmol) of 1-benzyl-4-(3-phenyl-2-hydroxypropyl)piperidine (Example 228, Step 2) and 0.775 g (5.16 mmol) of (S)-2-phenylpropionic acid in 10 mL of CH2Cl2 at 0° C. was added 1.32 g (6.9 mmol) of 1-[3-(dimethylamino)propyl]-3-ethylcarbodiimide hydrochloride and 0.1 g of 4-(dimethylamino)pyridine. The reaction was stirred for 5 h and let warm to rt. To the reaction mixture was added 80 mL of CH2Cl2 and the mixture was washed three times with 10% NaOH solution. The organic layer was washed with sat'd NaCl solution, dried over MgSO4, filtered and the filtrate was concentrated. The residue was purified by chromatography (silica, hexanes:ethyl acetate, 4:1) to give isomer 1a of the the title compound. Mass Spectrum (ESI) m/e=442 (M+1). [α]D=−3.7 (c=2.44, CHCl3).
