Procedure
To a solution of 0.70 g (1.52 mmol) of methyl 2-[(2-diacetylaminobenzyl)-(4-methoxybenzenesulfonyl)amino]acrylate in 5 ml of anhydrous methanol was added 0.332 g (3.95 mmol) of anhydrous sodium bicarbonate. The mixture was stirred at room temperature overnight and the solvent removed under vacuum. To the residue was added ethyl acetate and H2O. The organic layer was separated, washed with brine and dried with Na2SO4. The solvent was removed and the residue dried under vacuum to give 0.59 g of white crystals, m.p. 150-155° C.
