実験手順

A mixture of 1.50 g (2.9 mmol) of 2-(R)-(1-(3,5-bis(tri-fluoromethyl)phenyl)ethenyloxy)-3-(S)-phenyl-4-benzyl morpholine (from Example 68) and 750 mg 10% palladium on carbon catalyst in 25 mL of 3:2 v/v isopropanol/ethyl acetate was stirred under an atmosphere of hydrogen for 48 hours. The catalyst was filtered onto a pad of Celite; the reaction flask and filter pad were rinsed with 500 mL of ethyl acetate. The filtrate was concentrated in vacuo. Flash chromatography on 60 g of silica gel using 2:1 v/v hexanes/ether, then 2:1 v/v hexanes/ether afforded 106 mg of 2-(R)-(1-(S)-(3,5-bis(tri-fluoromethyl)phenyl)ethoxy)-3-(S)-phenyl morpholine and 899 mg of 2-(R)-(1-(R)-(3,5-bis(trifluoromethyl)phenyl)ethoxy)-3-(S)-phenyl morpholine, both as oils (84% total yield).
