Reaction Steps

A 4M solution of HCl in 1,4-dioxane (0.55 mL; 2.21 mmol; 4 eq.) was added to a suspension of 4-[2-(6-chloro-1,1,5,7-tetramethyl-1H,3H-2,4,7a,8-tetraaza-cyclopenta[a]indene-2-carbonyl)-phenoxy]-piperidine-1-carboxylic acid tert-butyl ester (306 mg; 0.55 mmol; 1 eq.) in 1,4-dioxane (6 mL) followed by water (604) and the resulting mixture was stirred at room temperature for 16 hours. A 4M solution of HCl in 1,4-dioxane (0.55 mL; 2.21 mmol; 4 eq.) was added and the resulting mixture was stirred at room temperature for 3 hours. Concentration in afforded the title compound (34 mg, quantitative) as an orange solid. 1H NMR (DMSO-d6) δ 9.09 (br s, 1H), 8.76 (br s, 1H), 7.48-7.38 (m, 1H), 7.37-7.17 (m, 2H), 7.06 (t, J=7.1 Hz, 1H), 4.85-4.67 (m, 1H), 4.41 (s, 2H), 3.05 (s, 4H), 2.84 (s, 3H), 2.54 (s, 3H), 2.06 (br s, 2H), 1.90 (s, 6H), 1.87-1.71 (m, 2H).
