実験手順

The title compound was prepared as described for Example 1 using 2-chloroisonicotinic acid and 1-methylpiperazine. The crude product was purified on a silica gel column using chloroform/methanolkconc. NH3(aq), (100:10:1), as the eluent to give the title compound as a colorless oil. Yield: 68%: 1H NMR (CDCl3, 400 MHz) δ 8.51 (d, J=5 Hz, 1 H), 7.57 (s, 1 H), 7.43 (dd, J=5, 1 Hz, 1 H), 3.66-3.58 (m, 2 H), 3.28-3.21 (m, 2 H), 2.41-2.34 (m, 2 H), 2.30-2.24 (m, 2 H), 2.20 (s, 3 H); MS (TSP) niz 240 (M++1).
