HCID 19372000Methyl 12-aminododecanoate--hydrogen chloride (1/1)Yield 60%

Procedure

MeOH (40 ml) was cooled to 0-50° C., and SOCl2 (4 ml) was added drop wise with stirring during 30 minutes. 12-Aminododecanoic acid (3 g, 13.9 mmol) was added and the resulting suspension was stirred at 0-5° C. while the ice in cooling bath melted and allowed to warm to room temperature during 16 hours. The mixture was filtered and the solid was dried by suction to afford 2.23 g (60%) of 12-aminododecanoic acid methyl ester hydrochloride. From the mother liquor a further batch of 0.92 g (25%) was isolated.
