Procedure
To a solution of [3-isopropyl-4-(2-benzothiazolylaminocarbonylmethoxy)benzoyl]methyltriphenylphosphonium chloride (3.3 g) in methanol (50 ml) is added DBU (1 ml), and the mixture is stirred at room temperature for two hours. The precipitated crystals are collected by filtration, washed with methanol, and dried to give [3-isopropyl-4-(2-benzothiazolylaminocarbonylmethoxy)benzoyl]methylenetriphenylphosphorane (2.27 g).
