Procedure
The title compound was synthesised following the procedure described for Compound 2C, except that Compound 3A was used instead of Compound 2B. The reaction was carried out at 40° C. Treatment of the reaction mixture with sodium dithionite and extraction with chloroform afforded a crude which was rinsed with 50 mL of ethyl acetate, boiled for 2 hours and filtered to give a first crop of Compound 3B. The mother liquor was evaporated and the residue was purified by flash chromatography (ethyl acetate/petroleum ether/glacial acetic acid 50:50:1) to give a second crop of Compound 3B. Total yield: 34%.
