Triethylamine → HCID 21409982, compound

Participants

Reaction Steps

A solution of 5.0 g. (16 mmole) of 5-chloro-2-(2-chloroethylmethylamino)benzophenone, 3.75 g. (50 mmole) of 3-aminopropanol, 50 ml. of triethylamine and 250 ml. of ethanol was stirred at reflux for 48 hours. The reaction mixture was then evaporated to a residue which was washed with water, dissolved in methylene chloride and chromatographed over a column of Florisil. The first fraction yielded the recovery of 2.7 g. of starting material. Elution with acetone, ethanol, methanol and finally with ammonial methanol gave a compound of very low Rf on fluorescent silica eluted with ethanol. Crystallization from acetone and recrystallizations from ether-petroleum ether gave the above-titled product as colorless prisms, m.p. 142°-144°.
