HCID 166792573-cyclobutyl-1-(1H-pyrrolo[2,3-b]pyridin-2-yl)imidazo[1,5-a]pyrazin-8-amine

Procedure

3-Cyclobutyl-1-[1-(2-trimethylsilylethoxymethyl)-1H-pyrrolo[2,3-b]pyridin-2-yl]imidazo[1,5-α]pyrazin-8-amine (35 mg, 0.08 mmol) was stirred with concentrated HCl for 15 min. The mixture was thien concentrated in vacuo and purified via mass directed preparative HPLC to afford the title compound. 1H NMR (400 MHz DMSO-d6) δ 1.92-2.00 (m, 1H), 2.07-2.14 (m, 1H), 2.43-2.47 (m, 4H), 3.93-4.01 (m, 1H), 6.35-6.49 (Us, 2H), 6.64-6.70 (m, 1H), 7.03-7.10 (m, 2H), 7.39-7.49 (m, 1H), 7.95-8.00 (m, 1H), 8.18-8.23 (m, 1H), 11.91 (bs, 1H). MS (ES+): m/z: 305.17 [MH+].
