The synthetic route is as follows.

To a suspension of 6-methyl-3-(tetrahydro-2H-pyran-4-yl)imidazo[1 ,5-a]pyrazin-8(7/-/)-one (100 mg, 429 mol) in dry DMF (2 mL) was added Cs2C03 (279 mg, 858 Mmol) and 5- (bromomethyl)benzo[d][1 ,3]dioxole (138 mg, 643 imol). The mixture was bubbled with 2 for 2 min and heated at 60C for 16 hours. The mixture was concentrated. DCM (30 mL) was added to the residue. It was filtered and the filter cake was washed with DCM (20 mL). The filtrate was concentrated and purified by flash chromatography on silica gel (10%~100% ethyl acetate in petroleum ether) to give 7-(benzo[d][1 ,3]dioxol-5-ylmethyl)-6-methyl-3- (tetrahydro-2H-pyran-4-yl)imidazo[1 ,5-a]pyrazin-8(7/-/)-one (81.74 mg, 52% yield). (1018) 1H NMR (CDCIa 400 MHz): delta 7.92 (s, 1 H), 6.76 – 6.69 (m, 4H), 5.95 – 5.93 (m, 2H), 5.13 (s, 2H), 4.14 – 4.11 (m, 2H), 3.61 – 3.55 (m, 2H), 3.10 – 3.05 (m, 1 H), 2.21 (s, 3H), 2.20 – 2.10 (m, 2H), 1.90 – 1.86 (m, 2H). (1019) LC-MS: fR = 2.245 min (method 3), m/z = 368.2 [M + H]+.
