実験手順

4-{3-[2-Methyl-4-(3-methyl-4,10-dihydro-3H-2,3,4,9-tetraaza-benzo[f]azulene-9-carbonyl)-phenyl]-propionyloxymethyl}-piperidine-1-carboxylic acid benzyl ester from Example E77.1 (44 mg, 0.07 mmol) was dissolved in methanol (5 ml) and hydrogenated over 10% Pd/C catalyst (5 mg) for 2 h. The mixture was filtered through Celite® filter agent and the filtrate concentrated in vacuo to give a white powder identified as the title compound (34 mg, 98%).
