Reaction Steps

Under a nitrogen atmosphere, a solution of 5-aminolevulinic acid methyl hydrochloride (1.0 g, 5.5 mmol) and triethylamine (2.3 mL, 16.5 mmol) in dichloromethane (50 mL) was cooled to 0° C., and benzoyl chloride (0.7 mL, 6.1 mmol) was then added to the solution. The obtained mixture was stirred at room temperature for 3 hours. Thereafter, water was added to the reaction solution, and it was then extracted with ethyl acetate. The organic layer was washed with a saturated saline and was then dried over sodium sulfate. The solvent was distilled away, and the obtained residue was then purified by silica gel column chromatography (hexane/ethyl acetate), so as to obtain the title compound (1.29 g, yield: 94%).
