Reaction Steps
A solution of the intermediate (5.4 g, 18.5 mmol) of step B, Pd(OH)2/C (0.3 g) in MeOH (200 mL) was stirred under hydrogen at 55 psi overnight. The catalyst was filtered off and the filtrate was concentrated to give 3.7 g of the desired product as a solid. MS calculated (M+H)+ 203. found 203.
