Abstract

1,237,067. Aminoalkyl thioethers. EASTMAN KODAK CO. 23 Jan., 1969 [29 Jan., 1968], No. 3883/69. Heading C2C. [Also in Divisions C3 and G2] 3-Methylthiopropylamine is prepared by adding methanethiol followed by 3-homopropylamine hydrobromide to a solution of sodium methoxide in methanol at 0‹ C. 3 - (2 - Diethylaminoethylthio) propanol is prepared similarly using 2-diethylaminoethanethiol hydrochloride and 3-bromopropanol. 2-Methylthioethylamine is prepared by cooling to - 5‹ C. a solution of methanethiol and sodium methoxide in methanol and adding ethyleneimine over a 20-minute period.
