Participants

Reaction Steps

To a suspension of tert-butyl 4-(3-(2-aminonicotinoyl)isoquinolin-1-yl)-1,4-diazepane-1-carboxylate (18 mg, 0.04 mmol) in 1,4-dioxane (1 ml) was added 4 M HCl in 1,4-dioxane (0.5 ml). The resulting mixture was stirred at room temperature for 5 hours. The reaction mixture was concentrated to dryness to leave title compound as a solid (16.6 mg, 98% yield). 1H NMR (CD3OD, 400 MHz) δ 2.25-2.32 (2H, s), 3.40-3.45 (2H, m), 3.55-3.60 (2H, m), 3.90-3.95 (2H, m), 4.07-4.12 (2H, m), 7.14-7.17 (1H, t), 7.81-7.89 (2H, m), 8.10-8.12 (1H, d), 8.17 (1H, s), 8.22-8.24 (1H, d), 8.29-8.31 (1H, d), 8.98-9.00 (1H, d); MS (ES+) 348.
