A solution of 8-chloro-3-((3aR,4S,6aS)-2,2-dimethyltetrahydrothieno[3,4-d][1,3]dioxol-4-yl)-[1,2,4]triazolo[4, 3-a]pyrazine (500 mg, 1.60 mmol), (3-chlorophenyl)methanamine (0.39 mL, 3.2 mmol) and TEA (0.68 mL, 4.8 mmol) in EtOH (8.0 mL) was stirred at 80° C. for 18 h. The reaction mixture was cooled to room temperature, diluted with DCM and washed with water and brine. The separated organic layer was dried over Na2SO4, filtered and concentrated in vacuo. The residue was purified by MPLC on SiO2 (2-5percent MeOH in DCM) to give N-(3-chlorobenzyl)-3-((3aR,4S,6aS)-2,2-dimethyltetrahydrothieno[3,4-d][1,3]dioxol-4-yl)-[1,2,4]triazolo[4,3-a]pyrazin-8-amine (2.40 g, 90percent) as a yellow oil. 1H-NMR (CDCl3, 400 MHz): delta 7.41 (m, 2H), 7.27 (m, 3H), 7.24 (d, J=4.8 Hz, 1H), 5.75 (d, J=5.2 Hz, 1H), 5.31 (t, J=4.0 Hz, 1H), 4.62 (s, 1H), 2.95 (m, 2H), 1.59 (s, 3H), 1.42 (s, 3H).
The synthetic route of 4152-90-3 has been constantly updated, and we look forward to future research findings.
