Participants

Reaction Steps

A mixture of 3-cyclobutyl-1-(1,2,3,6-tetrahydropyridin-4-yl)-imidazo[1,5-a]pyrazin-8-ylamine (20.0 mg, 0.0742 mmol), benzenesulfonyl chloride (9.48 uL, 0.0742 mmol), DIEA (0.0647 mL, 0.371 mmol) and DMF (1 mL, 0.01 mol) was stirred at rt for 10 min. The reaction mixture was directly given for Gilson HPLC purification. The fractions containing the pure product were concentrated in vacuo to afford the title compound as a yellow solid. 1H NMR (400 MHz, CDCl3): δ=2.03 (dt, J=8.84, 2.65 Hz, 1H) 2.09-2.24 (m, 1H) 239-2.59 (m, 4H) 2.81 (d, J=1.77 Hz, 2H) 3.50 (t, J=5.68 Hz, 2H) 3.72 (quin, J=8.53 Hz, 1H) 3.85 (t, J=2.91 Hz, 2H) 5.93 (t, J=1.52 Hz, 1H) 6.82 (d, J=5.56 Hz, 1H) 6.99 (d, J=5.56 Hz, 1H) 7.55-7.69 (m, 3H) 7.86-7.90 (m, 2H). MS (ES+): m/z 409.99 (100) [MH+]. HPLC: tR=2.29 min (OpenLynx, polar—5 min).
