HCID 12959377[(8-Bromooctyl)oxy]benzeneYield 75%

Procedure

Preparation analogously to Example 38 by the reaction of sodium phenolate with 1,8-dibromooctane to give 8-phenoxy-1-bromooctane (b.p.11 =196°-202°; yield 75%) which is reacted with excess 5-amino-5-desoxy-1.4;3.6-dianhydro-L-iditol 2-nitrate. Isolation is hydrochloride. Yield, after recrystallisation from ethanol/isopropanol: 62%.
