Reaction Steps

A solution of (RS)-tert-butoxycarbonylamino-(3-cyclohexylamino-phenyl)-acetic acid methyl ester (200 mg) in dioxane (5 ml) was treated with 4M HCl in dioxane (2.76 ml) and stirred at r.t. overnight, then concentrated. The crude product was purified by column chromatography (silica gel; gradient: CH2Cl2->CH2Cl2/MeOH 9:1) to give (RS)-amino-(3-cyclohexylamino-phenyl)-acetic acid methyl ester (126 mg, 87%) as light yellow viscous oil.
