Procedure

Methanesulfonyl chloride (4.40 μL, 0.057 mmol was added to a mixture of 1-{trans-4-[8-amino-1-(1H-indol-2-yl)imidazo[1,5-a]pyrazin-3-yl]cyclohexyl}methanamine (20.5 mg, 0.057 mol) and PS-DIEA (3.90 mmol/g loading; 60 mg, 0.2 mmol) in DCM (1.14 mL). The reaction mixture was stirred for 30 min at r.t. for 18 h. The crude reaction mixture was then concentrated and residue purified by mass directed preparative HPLC to afford 4 mg of desired product MS (ES+): m/z 439.10 (100) [MH+]. 1H NMR (CD3OD, 400 MHz): δ 8.24 (br s, 2H), 7.61 (m, 2H), 7.46 (dd, J=8.4, 0.8 Hz, 1H), 7.19 (ddd, J=7.2, 1.2, 1.2 Hz, 1H), 7.08 (ddd, J=7.2, 1.2, 1.2 Hz, 1H), 6.75 (d, J=0.8 Hz, 1H), 3.14 (m, 1H), 2.07 (m, 4H), 1.85 (m, 2H), 1.64 (m, 1H), 1.26 (m, 2H).
