Reaction Steps

To a solution of 3′-({[N-(tert-butoxycarbonyl)glycyl](methyl)amino}methyl)biphenyl-4-carboxylic acid (9 mg) in DMF (1 ml) was added HOBt (2 mg) and ethylamine (2 mg), and PS-Carbodiimide (manufactured by Biotage AB) (100 mg) was added thereto, followed by shaking overnight. Thereafter, PS-Isocyanate (manufactured by Biotage AB) and MP-Carbonate (manufactured by Biotage AB) were added in an amount of 50 mg, and DMF (0.5 ml) was further added thereto, followed by shaking for 2 hours. The insoluble material was filtered and the filtrate was concentrated. To the obtained residue was added MeOH (0.5 ml), and a 4 M hydrogen chloride/EtOAc solution (0.5 ml) was added thereto, followed by shaking for 1 hour. Thereafter, the reaction mixture was concentrated to obtain N-ethyl-3′-{[glycyl(methyl)amino]methyl}biphenyl-4-carboxamide (15.4 mg).
