反応手順

L-arginine (17.4 g, 0.1 mmols) were dissolved in 100 ml of water in a three-necked round flask, and 100 ml of propanol were added thereto. Dodecyl glycidyl ether [made by Sakamoto Yakuhin Kogyo Co., Ltd., 24.2 g (0.1 mols)] was added thereto dropwise over a period of 30 minutes while being heat-stirred under reflux, and the mixture was stirred as such under reflux, for 3 hours. After it was identified through TLC and gas chromatography that dodecyl glycidyl ether disappeared, the residue was neutralized with 10.1 g (0.1 mols) of 36-% hydrochloric acid. The reaction solution was concentrated under reduced pressure, and the residue was purified through silica gel column chromatography (Kieselgel 60 made by Merck & Co., Inc., eluent--mixture of chloroform, methanol and acetic acid at a ratio of 3:1:0.5) to give 15.0 g of N-(2-hydroxy-3-dodecyloxypropyl)-L-arginine hydrochloride in a yield of 36.0%.
