Yield:1269755-53-4 99.7%

Reaction Conditions:

with palladium 10% on activated carbon;hydrogen;acetic acid at 50;

Steps:

PREPARATION OF INTERMEDIATE 114

A hydrogenation flask was charged with AcOH (500 mL) and then 10% palladium on active carbon (19.52 g, 18.34 mmol) was added. Intermediate 113 (18.81 g, 91.69 mmol) was added and the mixture was hydrogenated at 50 °C overnight. The mixture was filtered over dicalite and the filtrate was evaporated to yield intermediate 114 (19.3 g, 99.7% yield), which was used in the next step without further purification
