Participants

Reaction Steps

To a solution of 5-chloro-3,4-bis(p-methoxybenzyloxy)benzoic acid (0.75 g: 1.75 mMol.) and 1-hydroxybenzotriazole (0.26 g: 1.1 Eq.) in tetrahydrofuran (15 ml) is added dicyclohexylcarbodiimide (0.40 g: 1.1 Eq.). After 1 hour stirring, to the mixture is added N-methylpiperazine (0.44 ml: 2.3 Eq.), and the mixture is stirred for 1 hour. The reaction mixture is filtered to remove solid and concentrated under reduced pressure to give 1-(5-chloro-3,4-bis(p-methoxybenzyloxy)benzoyl)-4-methylpiperazine (0.86 g). Yield: 96%.
