Procedure

Intermediate 63 (0.2 g, 0.62 mM) was dissolved in 40 ml of chloroform. To it was added p-anisidine (0.21 g, 1.66 mM), 0.19 g triethylamine and the reaction was refluxed for 18 hrs. Solvent was evaporated and the residue was extracted in ethyl acetate. The organic layer was washed with 10% HCl solution, brine and then dried over anhydrous Na2SO4. It was then evaporated to obtain the crude residue which was then purified over silica gel column using ethylacetate-hexane system to obtain the desired compound as beige solid with a yield of 65% (0.16 g); mp 190-192° C.
