Reaction Steps
To a solution of 4-(4-aminophenyl)butanoic acid (180 mg, 1 mmol) in a mixture of THF (4 ml), MeOH (1 ml) and dichloromethane (1 ml) in a 20-mL vial was added dropwise (trimethylsilyl)diazo-methane (1 ml, 2N in hexane) at 0° C. After the addition was complete, the resulting mixture was stirred at room temperature for 1 hr. The volatile material was removed under reduced pressure and the residue was purified by chromatography on silica gel using hexane/dichloromethane (2:1) followed by dichloromethane as eluent to give methyl 4-(4-aminophenyl)butanoate as an yellowish oil (55 mg, 28% yield).
