Abstract
Aminoalkyl esters of carbocyclic acids are prepared by esterifying the acids with alkylene glycols, with the aid of gaseous hydrogen chloride or hydrogen bromide, and treating the halogenalkyl esters so obtained with amines. Aliphatic aminoalcohols may be obtained by saponifying the aminoalkyl esters. In the examples: (1) p-hydroxybenzoic acid is heated with trimethylene glycol while hydrogen chloride is passed in, and the g -chloropropyl ester so produced is isolated and heated with diethylamine; p-hydroxybenzoic acid g -diethylamino propyl ester is produced, and may then be isolated and saponified to yield g -diethylaminopropanol; (2) anisic acid is esterified with ethylene glycol, with the aid of hydrogen chloride, to yield anisic acid b -chlorethyl ester, and the latter is heated with diethylamine to yield the b -diethylaminoethyl ester; this may then be saponified to yield b -diethylaminoethanol; (3) similarly, p-hydroxybenzoic acid and propylene glycol yield p-hydroxybenzoic acid p-chlorisopropyl ester, which is reacted with diethylamine to yield the b -diethylaminoisopropyl ester.
