Procedure

Into a 20 mL vial was placed 3-(4-(4-phenoxyphenoxy)pyridin-3-yl)aniline (30.00 mg, 0.08 mmol), N,N-diethylethanamine (0.02 mL, 0.17 mmol) suspended in 1-methylpyrrolidin-2-one (0.35 mL) and dichloromethane (2.00 mL). The resulting mixture was cooled to 0° C. Added acryloyl chloride (0.02 mL, 0.25 mmol). The ice bath was left to melt and the reaction mixture was stirred at rt overnight. The reaction mixture was purified using Biotage column chromatography eluting 0-40% MeOH in EtOAc. Fractions containing the desired product were combined and concentrated. Purified using prep-HPLC eluting 25-55% CH3CN in 0.1% TFA in H2O. Fractions containing the desired product were combined and lyophilized overnight to afford N-(3-(4-(4-phenoxyphenoxy)pyridin-3-yl)phenyl)acrylamide as a white solid (12.00 mg, 35% yield). HPLC purity: 100%, RT=4.235 min. MS: m/z=409 [M+H]+, RT=3.38 min. 1H-NMR (DMSO-d6) δ 10.23 (s, 1H), 8.52 (s, 1H), 8.43 (d, 1H), 7.95 (s, 1H), 7.71 (d, 1H), 7.44-7.33 (m, 4H), 7.19 (d, 2H), 7.13 (t, 1H), 7.09 (d, 2H), 7.02 (d, 2H), 6.80 (d, 1H), 6.45 (dd, 1H), 6.26 (d, 1H), 5.75 (d, 1H).
