The product from Example 5 (7 g) in 250 mL of methanol was treated with 20% Pd/C (1 g) and shaken on a Parr apparatus under a hydrogen atmosphere (50 psi) for 16 h at ambient temperature. The catalyst was removed by filtration and the filtrate evaporated to give the product as a purple solid (6.3 g, 99% yield) that was used immediately without further purification.
