Reaction Steps
Copper (I) cyanide (550 mg, 6 mmol) was added to a solution of methyl 2-methoxy-5-bromo-4-iso-propylbenzoate (861 mg) in N-methyl-2-pyrrolidinone (30 ml). The mixture was stirred under argon and boiled under reflux for 4 h. The mixture was cooled, poured into excess ice/water and ethyl acetate and filtered. The organic phase was separated, washed with water, brine and dried(MgSO4). Evaporation gave a crude brown solid which was purified by chromatography on silica gel eluting with ethyl acetate/n-hexane (1:4). The product was obtained as a white solid (523 mg).
