Reaction Steps

11.4 g (45.4 mmol) 11-bromo-1-undecanol, 11.0 g (47.7 mmol) 3,5-dinitrobenzoyl chloride and 54 mg 4-dimethylaminopyridine were dissolved in 94 ml dichloromethane. The solution was subsequently cooled to 0° C. and then 18.3 ml is (227 mmol) pyridine was added dropwise, in the course of 25 minutes. After 4.5 hours at 0° C. the reaction mixture was partitioned between dichloromethane and water. The organic phase was washed repeatedly with water, dried over sodium sulfate, filtered and concentrated by rotary evaporation. Chromatography of the residue on 200 g silica gel using toluene yielded 18.1 g (90%) 3,5-dinitrobenzoic acid 11-bromoundecyl ester as yellow powder.
