{1-[4-(5H,11H-Benzo[e]pyrrolo[1,2-a][1,4]diazepine-10-carbonyl)-2-methylbenzylcarbamoyl]-8-fluoro-1,2-dihydroquinolin-4-yl}acetic acid ethyl ester → {1-[4-(5H,11H-Benzo[e]pyrrolo[1,2-a][1,4]diazepine-10-carbonyl)-2-methylbenzylcarbamoyl]-8-fluoro-1,2,3,4-tetrahydroquinolin-4-yl}acetic acid ethyl ester

Reaction Steps

A mixture (75 mg, 0.13 mmol) of {1-[4-(5H,11H-benzo[e]pyrrolo[1,2-a][1,4]diazepine-10-carbonyl)-2-methylbenzylcarbamoyl]-8-fluoro-2,3-dihydro-1H-quinolin-4-ylidene}acetic acid ethyl ester from Example 4 and {1-[4-(5H,11H-benzo[e]pyrrolo[1,2-a][1,4]diazepine-10-carbonyl)-2-methyl-benzylcarbamoyl]-8-fluoro-1,2-dihydroquinolin-4-yl]acetic acid ethyl ester from Example 5 was dissolved in methanol (50 ml). To the solution was added a catalytic amount of 10% palladium on carbon and the mixture was stirred under a hydrogen atmosphere for 6 h. The mixture was filtered through Celite® and evaporated. The mixture was redissolved in methanol (50 ml), a further catalytic amount of 10% palladium on carbon was added and the mixture stirred under a hydrogen atmosphere for 3 h. The mixture was filtered and evaporated to give a white solid, yield 74 mg (97%).
