실험 절차
5-Chloro-2-methoxyphenylisocyanate (5.3 g, 29 mmol) was dissolved in THF (250 ml) under N2 and heated to 60° C. To this solution was added 2-aminoacetophenone-HCl (5 g, 29 mmol) followed by triethylamine (3.8 g, 30 mmol). After being stirred 1.5 h, the reaction mixture was diluted with ethyl acetate (2 vol) and washed with 1N HCl solution, saturated NaCO3 solution, and brine before being dried, MgSO4. Concentration gave a solid which was washed with diethylether 6 g (65%). mp 171-173° C.; IR(KBr, υ=cm−1) 3336, 1706, 1644, 1600, 1560, 1482, 1262, 1220, 1182, 1126; 1H NMR (300 MHz, CDCl3) δ 3.79 (3H, s), 4.84 (2H, d, J=4.3 Hz), 5.97 (1H, br.s), 6.71 (1H, d, J=8.7 Hz), 6.88 (1H, dd, J=8.7 Hz, 2.5 Hz), 7.97-8.00 (2H, m), 8.18 (1H, d, J=2.5 Hz); MS(DCl)m/z: 319(MH+); Anal. calcd. for C16H15ClN2O3: C, 60.29; H, 4.74; N, 8.79.
