실험 절차
N,N-Dimethylformamide dimethyl acetal (1.1 ml, 8.3 mmol) was combined with 1-benzhydryl-3-methylaminoazetidine-3-carboxylic acid amide (I-(29A-7)b; 153 mg, 0.52 mmol) and heated to reflux. After 3 hours, the suspension was cooled and extracted from saturated aqueous NaHCO3 with ethyl acetate. The combined extracts were dried (Na2SO4), and concentrated, in vacuo, to afford I-(29A-7)c as a solid (152 mg, 96%): +ES MS (M+1) 306.3; 1H NMR (400 MHz, CD3OD) δ 8.42 (s, 1H), 7.47 (d, J=7.5 Hz, 4H), 7.27 (t, J=7.5 Hz, 4H), 7.17 (t, J=7.5 Hz, 2H), 4.57 (s, 1H), 3.58 (s, 3H), 3.55 (d, J=10.0 Hz, 2H), 3.34 (d, J=10.0 Hz, 2H).
