実験手順

Chloroacetonitrile (6.63 mL, 105 mmol) was added to a stirred solution of 1-(3-bromophenyl)-2-methylpropan-2-ol) (Preparation 16) (12.0 g, 52.0 mmol) in acetic acid (25 mL) at room temperature. The resulting solution was cooled to 0° C. and concentrated sulfuric acid (25 mL) was added keeping the temperature <10° C. The resulting solution was left to stir for 1 hour and then poured onto ice and basified by the addition of solid potassium carbonate. The product was extracted with ethyl acetate (2×500 mL), the organics combined and washed with water (50 mL), dried (sodium sulfate) and the solvent removed in vacuo to afford the title compound as an orange solid (16.08 g).
