An anhydrous DMF (2 mL) solution of 3-(8-amino-3-cyclobutyl-imidazo[1,5-a]pyrazin-1-yl)-phenol (50 mg, 0.179 mmol) and K2CO3 (27 mg, 0.197 mmol) was charged with 1-bromomethyl-4-fluoro-benzene (7) (24 μL, 0.197 mmol) and stirred 12 h at 40° C. The reaction mixture was partitioned between CHCl3 and H2O and separated. The aqueous layer was re-extracted with CHCl3 (3×) and the combined organic fractions were washed with H2O (1×), brine (1×), dried over Na2SO4, filtered and concentrated in vacuo. The crude mixture was purified by MDP resulting in a light tan/waxy solid; 1H NMR (CDCl3, 400 MHz) δ 1.99-2.08 (m, 1H), 2.11-2.25 (m, 1H), 2.44-2.55 (m, 2H), 2.58-2.70 (m, 2H), 3.75-3.88 (m, 1H), 5.06 (brs, 2H), 5.10 (s, 2H), 6.98-7.15 (m, 5H); 7.20-7.34 (m, 3H), 7.35-7.47 (m, 3H); MS (ES+): m/z 389.14.
