Reaction Steps

A 4N solution of HCl in dioxane (1.0 mL, 4 mmol) was added to a solution of {1-[2-(6-chloro-5,7-dimethyl-1H,3H-2,4,7a,8-tetraaza-cyclopenta[a]indene-2-carbonyl)-benzyl]-piperidin-4-yl}-carbamic acid tert-butyl ester (136 mg, 0.24 mmol) in dioxane (1.0 mL). After 3 hours of stirring at RT, the precipitate was filtered off and washed with dioxane (2×). The solid was dissolved in water (2 ml) and lyophilized to give the title compound as an off-white powder (82 mg, 64%). 1H NMR (300 MHz, DMSO-d6) δ 10.97-10.60 (m, 1H), 8.63-8.24 (m, 3H), 8.15-7.98 (m, 1H), 7.76-7.41 (m, 3H), 5.08-4.86 (m, 2H), 4.73-4.48 (m, 2H), 4.44-4.17 (m, 2H), 3.60-2.96 (m, 5H), 2.85 (s, 1.5H), 2.81 (s, 1.5H), 2.63 (s, 1.5H), 2.56 (s, 1.5H), 2.23-1.78 (m, 4H). HPLC (max plot) 96.1%, Rt 2.23 min. UPLC/MS: (MS+) 439.4 ([M+H]+).
