Ammonium Chloride → HCID 57827301, compound

Participants

Reaction Steps

Potassium tert-butoxide (9.93 g) was added to a solution of 2-fluorophenylacetonitrile (10 g), toluene-4-sulfonic acid 2-allyloxyethyl ester (19 g) and 18-crown-6 (3.91 g) in tetrahydrofuran (400 mL) under ice-cooling. The reaction solution was stirred at the same temperature for 10 minutes. The reaction solution was warmed to room temperature and further stirred for four hours. Aqueous ammonium chloride and ethyl acetate were added to the reaction solution, and the organic layer was separated. The organic layer was washed with saturated aqueous sodium chloride. The organic layer was dried over anhydrous magnesium sulfate. The organic layer was concentrated under reduced pressure. The residue was purified by silica gel column chromatography to obtain the title compound (10.9 g).
