Participants

Reaction Steps

N,N′-Diisopropylethylamine (1.05 ml, 6.03 mmol) was added to a flask charged with DMF solution mixture of (S)-(−)-3-Aminoquinuclidine dihydrochloride (400 mg, 2.01 mmol) and 4-Iodobenzoyl chloride (616 mg, 2.31 mmol). The clear yellow solution was stirred for 3 hours. The reaction mixture was worked up by addition of 1N sodium hydroxide aqueous solution and extracted twice with ethyl acetate, combined organic layer was washed with saturated brine solution, dried over sodium sulfate, filtered, and concentrated to crude clear oil. The crude oil was purified via preparative HPLC to obtain pure product of (S)-4-iodo-N-(quinuclidin-3-yl)benzamide, (460 mg, 64% yield). 1H NMR (400 MHz, Methanol-D4) δ (ppm): 7.85 (d, J=8 Hz, 2H), 7.60 (d, J=8 Hz, 2H), 4.12 (m, 1H), 3.31 (m, 1H), 2.99 (m, 1H), 2.84 (m, 4H), 2.02 (m, 1H), 1.90 (m, 1H), 1.78 (m, 2H), 1.54 (m, 1H). C14H17IN2O=356.04 LCMS (M+H): m/z 357
