Ethanol → Aminolevulinic acid phosphate

참여 물질

반응 단계

A 10.05 g (60.6 mmol) portion of δ-aminolevulinic acid hydrochloride and 4.5 ml (65.7 mmol) of 85% phosphoric acid were dissolved in 30 ml of purified water, and 5.83 g (62.7 mmol) of γ-picoline was added dropwise thereto while stirring. After completion of the dropwise addition and subsequent stirring at room temperature for 10 minutes, 400 ml of ethanol was added thereto and stirred. The thus precipitated precipitate was recovered by suction filtration and dried at room temperature for 19 hours under a reduced pressure. A 10.55 g (46.1 mmol) portion of δ-aminolevulinic acid phosphate was obtained at a yield of 77 mol %.
