실험 절차
5-[(2-Fluorophenyl)amino]-N-piperidin-4-yl-1,3,4-oxadiazole-2-carboxamide (Intermediate 101) (100 mg, 0.33 mmol) and methyl (6-chloro-1-oxidopyridin-3-yl)acetate (67 mg, 0.33 mmol) were heated with sodium hydrogen carbonate (56 mg, 0.66 mmol) in 2-methyl-2-butanol (4 mL) at 100° C. for 22 h. The reaction mixture was concentrated by evaporation and the residue was dissolved in DMSO then filtered and purified by preparative HPLC to give the title compound (50 mg, 32%) as a gum; 1H NMR δ 1.94-1.74 (m, 4H), 2.58-2.43 (m, 2H), 2.95-2.84 (m, 2H), 3.65 (s, 3H), 4.07-3.93 (m, 3H), 7.21-7.12 (m, 2H), 7.35-7.23 (m, 2H), 7.45-7.40 (m, 1H), 8.06-7.98 (m, 1H), 8.25-8.20 (m, 1H), 9.13 (d, 1H), 10.64 (s, 1H); MS m/e MH+ 471.
