Procedure

Conc. hydrochloric acid (sg. 1.18, 1.5 ml) was added to the compound from step b) (3.3 g) in methanol (30 ml) and the mixture stirred at room temperature overnight. The solvent was evaporated under reduced pressure and the residue partitioned between chloroform and water. The organic layer was separated and the aqueous layer extracted with dichloromethane. The combined organic extracts were dried (MgSO4) and the solvents removed under reduced pressure to give the subtitled compound as an orange oil.
