Procedure

A solution of 8-amino-N-(2-aminophenyl)-3-cyclobutylimidazo[1,5-a]pyrazine-1-carboxamide (40.0 mg, 0.124 mmol) in acetic acid (1.2 mL) was microwaved at 120° C. for 10 min (300 W). The resulting solution was purified mass directed preparative HPLC to afford 1-(1H-benzimidazol-2-yl)-3-cyclobutylimidazo[1,5-a]pyrazin-8-amine. 11-1 NMR (400 MHz, DMSO-d6) δ ppm 1.92-2.05 (m, 1 H) 2.07-2.21 (m, 1 H) 2.53-2.59 (m, 4 H) 3.91-4.06 (m, 1 H) 7.08 (d, J=4.80 Hz, 1 H) 7.16-7.26 (m, 2 H) 7.38 (d, J=4.80 Hz, 1 H) 7.44 (br. s., 1 H) 7.55 (d, J=8.08 Hz, 1 H) 7.62 (d, J=6.82 Hz, 1 H) 10.49 (br. s., 1 H) 12.76 (s, 1 H); MS (ES+): m/z 305.15 [MH+].
