Versuchsvorschrift

(4-Benzyloxy-phenyl)-(3-methyl-4,10-dihydro-3H-2,3,4,9-tetraaza-benzo[f]azulen-9-yl)-methanone from Example E75.1 (800 mg, 1.95 mmol) was dissolved in methanol (100 ml) and hydrogenated over 10% Pd/C catalyst (400 mg) for 7 h. The mixture was filtered through Celite® filter agent, washed with chloroform and methanol and the filtrate was concentrated in vacuo to yield the title compound (140 mg, 22%).
