Potassium Carbonate → 2-{[Methoxycarbonylmethyl-(toluene-4-sulfonyl)-amino]-methyl}-4-(pyridin-2-yloxy)-benzoic acid ethyl ester

Participants

Reaction Steps

A mixture of 2-bromomethyl-4-(pyridin-2-yloxy)-benzoic acid ethyl ester (855 mg, crude from previous step), Ts-Gly-OMe (502 mg), potassium carbonate (425 mg) and KI (32 mg) in DMF (10 mL) was stirred at rt overnight. Then the reaction mixture was diluted with EtOAc, washed with water, diluted NaCl sol and dried over anhydrous sodium sulfate, filtered, concentrated and the residue was column purified to give product (745 mg). LC MS ESI+: 499 (M+1)+.
