Reaction Steps

The hydrolysis of 6-({5-[(4-carbamimidoyl-phenylamino)-methyl]-3-hydroxy-2-methyl-pyridin-4 ylmethyl}-amino)-hexanoic acid (49) (100 mg, 0.2 mmol) was carried out in 6N hydrochloric acid for 2 hours. The solvent was then evaporated and the crude product purified by column chromatography on silica gel using a mixture of dichloromethane:methyl alcohol:30% ammonium hydroxide (5:3:1) as eluant to give 6-({3-benzyloxy-5-[(4-carbamimidoyl-phenylamino)-methyl]-2-methyl-pyridin-4-ylmethyl}-amino)-hexanoic acid (50).
