실험 절차

4-[3-(4-Fluorophenyl)-1-methyl-1H-pyrazol-4-yl]furo[3,4-b]pyridin-5(7H)-one (Example 1, step 5, 472 mg, 1.46 mmol) and benzyl amine (0.167 mL, 1.53 mmol) in acetic acid (4.7 mL) were heated at reflux for 18 hr, cooled and then concentrated to a brown solid. This material was stirred with diethyl ether (20 mL) for 10 min and then filtered to yield 450 mg (75%) of Ex 5-Step 1 product as a tan colored solid: LCMS m/z 413.5 (M+1); 1H NMR (400 MHz, CDCl3) δ 8.57 (d, J=5.2, 1H), 8.15 (s, 1H), 7.26-7.42 (m, 7H), 7.13 (d, J=5.3, 1H), 7.01 (dd, J=8.6, 8.6, 2H), 4.87 (s, 2H), 4.00 (s, 3H).
