The reaction mixture was stirred overnight on hydrogen gas pressure (50 psi) at 50° C. The reaction mixture was filtered through celite and concentrated to afford 0.25 g of the required product which was used for the next step without further purification. Percentage purity (LCMS): 70.8%, (M+1)=560.2+1
