Procedure
The product from step (vi) (1 g) was dissolved in ethanol (10 ml) and hydrazine monohydrate (1 ml) was added and stirred at ambient temperature for 10 h. The resultant was concentrated under reduced pressure and the residue suspended in DCM (10 ml) and stirred for 1 h. The suspension was filtered, washed with DCM. The solution was washed with water and dried. The solution was concentrated under reduced pressure to give the subtitled compound. Yield 700 mg.
