실험 절차

Prepared following the procedure of Example 1 from N-ethylformanilide and 2-aminopyridine. Vacuum distillation of the crude product gave pure 4 as a pale yellow oil: bp 164° C. @ 0.5 mm Hg. 1H-NMR (CDCl3) 8.83 (S, 1H), 8.30 (m,1H), 7.5-6.9 (m, 8H), 4.09 (q, 2H, J=7 Hz) 1.26 (t, 3H, J=7 Hz); IR(neat) 2990, 1620, 1570, 1500, 1460, 1440, 1390, 1230, 1130; MS (m/e) 225 (M+), 78 (base).
