Sodium Hydroxide → {4-[2-(Pyrid-3-yl)ethenyl]-2-phenylbenzoyl}methionine sodium salt

Participants

Reaction Steps

To a solution of the {4-[2-(pyrid-3-yl)ethenyl]-2-phenylbenzoyl}methionine methyl ester prepared in Example 210 (136 mg, 0.304 mmol) in methanol (2 mL) was added a solution of sodium hydroxide (0.979 N, 0.334 mL). After 14 hours, the solvent was evaporated in vacuo to give {4-[2-(pyrid-3-yl)ethenyl]-2-phenylbenzoyl}methionine sodium salt (141 mg, 100%). 1H NMR (300 MHz, DMSO-d6) δ 8.90 (d, 1H), 8.46 (dd, 1H), 8.07 (dt, 1H), 7.64 (m, 2H), 7.50-7.35 (m, 10H), 3.78 (m, 1H), 2.10 (m, 2H), 1.98 (s, 3H), 1.76 (m, 2H). MS (APCI+) m/e 433 (M+H)+.
