PROCEDURE
实验过程
N-(4-Chloro-3-iodophenyl)-6-(trifluoromethyl)-2-methylpyridine-3-carboxamide (220 mg, 0.5 mmol), 2-aminopyridine (40 mg, 0.42 mmol), potassium t-butoxide (66 mg, 0.59 mmol), Pd2(dba)3 (20 mg, 0.21 mmol), dppf (24 mg, 0.042 mmol) in toluene (2.1 mL) were heated to 100° C. for 1.5 days. The solution was cooled to 23° C., diluted with ether, filtered through celite, washed with ethyl acetate, and concentrated. Purified by reverse phase HPLC to yield N-(4-chloro-3-(pyridin-2-ylamino)phenyl)-6-(trifluoromethyl)-2-methylpyridine-3-carboxamide as a white solid: 1H NMR (CDCl3, 400 MHz) δ 11.53 (s, 1H), 9.68 (s, 1H), 8.05 (m, 2H), 7.85 (m, 2H), 7.55 (d, 1H), 7.26 (d, 1H), 7.13 (dd, 1H), 6.91 (t, 1H), 6.88 (d, 1H), 2.75 (s, 3H); MS (Q1) 407.0 (M)+.
