Dimethylformamide → (1R*,2R*,5S*,6R*)-8-Allyl-2-{[3,5-bis(trifluoromethyl)phenyl]methoxy}-6-(tert-butoxycarbonyl)-1-phenyl-8-azabicyclo[3.2.1]octane

Participants

Reaction Steps

A mixture of (1R*,2R*,5S*,6R*)-2-{[3,5-bis(trifluoromethyl)phenyl]methoxy}-6-(tert-butoxycarbonyl)-1-phenyl-8-azabicyclo[3.2.1]octane (Example 25; 424 mg, 0.8 mmol), potassium carbonate (770 mg), allyl bromide (0.5 ml) and N,N-dimethylforamide (3 ml) was stirred at room temperature for 3 days. The reaction mixture was treated with 1:1 mixture diethyl ether:iso-hexane, washed with water, dried (Na2SO4) and concentrated. The residue was purified by chromatography on silica gel (iso-hexane:diethyl ether) to give the title compound (362 mg, 79%).
