Participants

Reaction Steps

10% Palladium on carbon (60 mg, 0.06 mmol) was added to a solution of 7H-indolo[2,1-a][2]benzazepine-6,10-dicarboxamide, 13-cyclohexyl-N10-[(dimethylamino)sulfonyl]-3-methoxy-N6-methyl-N6-[2-(4-morpholinyl)-2-oxoethyl]- (59 mg, 0.09 mmol) in MeOH (3 mL) and the reaction mixture was vacuum flushed with nitrogen (3×) and then with hydrogen (3×). The reaction mixture was stirred under a balloon of hydrogen overnight. The reaction mixture was once again vacuum flushed with nitrogen (3×) and then with hydrogen (3×) and stirred under a balloon of hydrogen overnight. The solution was filtered through a pad of celite and concentrated to yield 5H-indolo[2,1-a][2]benzazepine-6,10-dicarboxamide, 13-cyclohexyl-N10-[(dimethylamino)sulfonyl]-6,7-dihydro-3-methoxy-N6-methyl-N6-[2-(4-morpholinyl)-2-oxoethyl]- (31 mg, 0.05 mmol, 53%) as a yellow solid. Mixture of atrope diastereomers: 1HNMR (500 MHz, CDCl3) δ 10.85 (br s, 1H), 8.07 (s, 1H), 7.85 (d, J=8.5 Hz, 1H), 7.70 (d, J=8.5 Hz, 1H), 7.34 (d, J=8.2 Hz, 1H), 6.93 (d, J=8.2 Hz, 1H), 6.91 (s, 1H), 4.75-4.33 (m, 2H), 3.88 (s, 3H), 3.94-2.44 (m, 13H), 3.31 (s, 3H), 3.02 (s, 6H), 2.95-2.84 (m, 1H), 2.19-1.17 (m, 10H). LCMS: m/e 678 (M−H)−, ret time 2.77 min, column A, 4 minute gradient.
