Reference of 140914-89-2, A common heterocyclic compound, 140914-89-2, name is 2-(Pyrazin-2-yl)acetic acid, molecular formula is C6H6N2O2, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
Intermediate 34 (300 mg, 0.75 mmol), 2-(pyrazin-2-yl)acetic acid (120 mg, 0.87 mmol), HATU (600 mg, 1.59 mmol), N-Ethyldiisopropyl amine (0.3 ml, 2.17 mmol) were dissolved in DMF (4 ml). This mixture was stirred at rt for 1 h. Reaction mass was poured in to water to obtain a solid. Solid was filtered and purified the solid by column chromatography on 60-120 silica gel using MeOH and DCM (5:95) as eluent to afford the titled compound (13 mg) as a Pale-brown solid. M.P.: 232-234C. JH-NMR (delta ppm, DMSO-<, 400 MHz): 12.74 (s, 1H), 10.90 (s, 1H), 8.65 (s, 1H), 8.57-8.52 (m, 2H), 7.98 (d, J 9.8, 1H), 7.40-7.36 (m, 2H), 7.35-7.25 (m, 1H), 7.18- 7.12 (m, 2H), 4.30 (d, J 13.3, 2H), 4.06 (s, 2H), 3.79 (s, 2H), 3.40-3.31 (m, 1H), 3.05 (t, J 12, 2H), 2.10 (d, J 10.7, 2H), 1.80-1.66 (m, 2H).
The synthetic route of 140914-89-2 has been constantly updated, and we look forward to future research findings.
