実験手順
Triethylamine (2.5 g, 25 mmol) is added dropwise at 0° to a solution of 1-ethoxycyclopropylammonium chloride (1.25 g, 9.15 mmol) and benzoyl chloride (1.4 g, 10 mmol) in dry tetrahydrofuran (20 ml). The precipitate is filtered off and the filtrate is evaporated in vacuo yielding a crystalline residue. Sublimation following by recrystallisation from cyclohexane gives N-(1-ethoxycyclopropyl)-benzamide, mp 108°-109° (0.95 g, 51%); NMR (60 MHz): δCDCl 3 = 0.90-1.38 (m, 4H), 1.16 (t, J=7 Hz, 3H), 3.77 (q, J=7 Hz, 2H), 7.0-8.0 (1 m and 1 br. s, total 6H).
