YieldReaction ConditionsOperation in experiment
89% Dissolve <strong>[60211-57-6]3,5-dichlorobenzyl alcohol</strong> (10.0 g, 56.0 mmol) in DMF (20 mL) and slowly add thionyl chloride (4.40 mL, 60.0 mmol) to the mixture, while cooling in a water bath. After stirring for IH, add K2CO3 (15.8 g, 110 mmol) and stir an additional Ih. Then add DMSO (50 mL) and sodium azide (5.60 g, 86 mmol) and stir the mixture overnight at RT. Dilute the mixture with water and extract with EtOAc. Wash the combined extracts with water and dry over Na2SO4. Concentrate to give the title compound (10.11 g, 89%) as an oil. Use without further purification. MS (ES) 201.0 (M+L) +.
68% With sodium azide; triphenylphosphine; In N,N-dimethyl-formamide; at 90℃; for 5h;Inert atmosphere; General procedure: 3,5-Dimethylbenzyl alcohol (21, 300 mg, 1.71 mmol), was added to a suspension of sodium azide (141 mg, 2.17 mmol) and triphenylphosphine (446 mg, 1.71 mmol) in DMF (10 mL) and the heated to 90 C, with a condenser attached. CCl4 (4 mL)was then added to the mixture, which was allowed to react at 90 C for a further 5 h. The reaction mixture was then cooled to rt and taken up in Et2O. The organic layer was washed with water and dried over MgSO4. The solvent was then removed in vacuo and the resulting crude oil was purified by silica gel chromatography (2%EtOAc/Hex) to yield 17 as a yellow oil (218 mg, 1.08 mmol, 68%).
