Reaction Steps

To dichloromethane (50 ml) are added (3-methoxy-4-carboxymethoxybenzoyl)methylenetriphenylphosphorane (5 g), 2-aminobenzothiazole (1.9 g), bis(2-oxo-3-oxazolidinyl)phosphinic chloride (2.93 g) and triethylamine (3.3 ml), and the mixture is stirred overnight. After the reaction is complete, the mixture is washed with an aqueous sodium hydrogen carbonate solution, and dried over magnesium sulfate to remove the solvent, and further recrystallized from toluene to give [3-methoxy-4-(2-benzothiazolylaminocarbonylmethoxy)benzoyl]methylenetriphenylphosphorane (5.17 g).
