Procedure

A mixture of the compound obtained in step e above (623 mg, 1.512 mmol) and 2 N HCl (20 mL) was refluxed for 2 h. The reaction mixture was cooled down and then extracted with EtOAc. The combined organic layers were dried and concentrated; the crude product was purified by silica gel column chromatography which gave the title compound as colourless oil (409 mg, 68%).
