Reaction Steps

The product obtained from example 3 (553 mg, 1.00 mmol) was dissolved in EtOAc (10 mL) and then hydrogenated using 10% Pd on charcoal as catalyst at atmospheric pressure for 2 h. The catalyst was filtered off and the filtrate was evaporated in vacuo to yield the title compound in 95% yield.
