Participants

Reaction Steps

Benzyl 4-((1E,4E)-2-amino-4-(dipropylcarbamoyl)-3H-benzo[b]azepin-8-yl)benzoate (0.025 g, 0.0504 mmol) was suspended in 1 ml of methanol, and 25 mgs of 10% Pd/C (Degussa type) was added and the mixture was hydrogenated under a balloon of hydrogen for one hour. This mixture was then filtered through GF/F filter paper, and the filtrate was concentrated to 16 mgs of 4-((1E,4E)-2-amino-4-(dipropylcarbamoyl)-3H-benzo[b]azepin-8-yl)benzoic acid (78%). 1H-NMR (400 MHz, DMSO-d6) δ 7.98-8.03 (m, 2H), 7.76-7.82 (m, 2H), 7.38-7.43 (m, 1H), 7.33-7.37 (m, 1H), 7.27-7.31 (m, 1H), 6.92 (br s, 1H), 6.76 (s, 1H), 3.28-3.36 (m, 4H, partially obscurred by water peak), 2.74 (s, 2H), 1.51-1.62 (m, 4H), 0.71-0.97 (m, 6H); m/z (APCI-pos) M+1=406.2.
