Benzylamine → HCID 19820422, compound

Participants

Reaction Steps

9.1 ml of benzylamine were added to a solution of 7.26 g of 2-(2-bromoethoxy)-1-[2-(2-bromoethyl)phenoxy]-4-chlorobenzene in 714 ml of xylene and the mixture was heated to reflux for 24 h. After cooling the precipitate was removed with suction, washed with toluene and the filtrate was evaporated to dryness. The residue was chromatographed over silica with toluene-ethanol (9:1) to yield 4,17 g (64%) of 3-chloro-7,8,9,10-tetrahydro-8-phenylmethyl-6H-dibenzo[b,j][1,4,7]dioxaazacycloundecine. Rf 0.7 (silica; toluene-ethanol 8:2).
