Procedure
The product of Example F (450 mg, 0.002 mole) was dissolved in 5 mls of benzene and 250 mg of thionyl chloride was added. The mixture was refluxed for one hour. After cooling, the solution was poured into dilute K2CO3 and extracted with ethyl acetate. The organic phase was dried over Na2SO4, stripped and chromatographed on silica gel using 5% ethyl acetate/hexane as the eluent to give 275 mg of the title compound as an oil (56% yield).
