Reaction Steps

A mixture of 2-chloro-3,4-bis(p-methoxybenzyloxy)benzoic acid (0.61 g: 1.42 mMol.) is reacted with 1-hydroxybenzotriazole (231 mg: 1.2 Eq.) and dicyclohexylcarbodiimide (352 mg: 1.2 Eq.) in tetrahydrofuran at room temperature for 1 hour, and then with N-methylpiperazine (0.32 ml: 2 Eq.) for 1 hour to give 1-(2-chloro-3,4-bis(p-methoxybenzyloxy)benzoyl)-4-methylpiperazine (0.72 g). Yield: 99%.
