Reaction Steps

A 4M solution of HCl in 1,4-dioxane (0.72 mL; 2.9 mmol; 15 eq.) was added to a solution of {2-[2-(6-chloro-5,7-dimethyl-1H,3H-2,4,7a,8-tetraaza-cyclopenta[a]indene-2-carbonyl)-5-fluoro-phenoxy]-ethyl}-methyl-carbamic acid tert-butyl ester (100 mg; 0.19 mmol; 1 eq.) in DCM (5 mL) and the reaction mixture was stirred at room temperature for 2 hours. The residue was suspended in hot MTBE, filtered and dried to afford the title compound (60 mg, 68%) as a pale yellow solid. 1H NMR (DMSO-d6) δ 8.92-8.69 (m, 2H), 7.50-7.38 (m, 1H), 7.24-7.13 (m, 1H), 7.00-6.90 (td, J=8.5, 8.0, 2.2 Hz, 1H), 4.89-4.77 (d, J=8.6 Hz, 2H), 4.65-4.51 (m, 2H), 4.41-4.32 (m, 2H), 3.27 (br s, 2H), 2.85 (s, 1.7H), 2.81 (s, 1.3H), 2.62 (s, 1.3H), 2.57 (s, 1.7H), 2.53 (s, 3H). HPLC (max plot) 97.0%, Rt 2.73 min. UPLC/MS: (MS+) 418.3 ([M+H]+).
