Related Products 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.
2-(9H-Carbazol-1-yl)aniline (50 mg, 0.194 mmol, 1 eq), 2-(pyrazin-2-yl)acetic acid (40 mg, 0.29 mmol, 1.5 eq) and DIPEA (162 muL, 0.929 mmol, 4.8 eq) were dissolved in DCM (2 mL, 0.1 M) and then had HATU (88 mg, 0.232 mmol, 1.2 eq) added before the solution was stirred for 16 h at room temperature. Upon reaction completion the crude mixture was concentrated onto silica gel before being purified by Isolera Biotage LPLC (CH/EA 8:2) to give 85 (32 mg, 0.084 mmol, 44%) as a white solid. Mpt: 189.0-191.0 C; vmax (cm-1) 3296, 1659, 1581, 1532, 1312, 1236, 738; 1H-NMR (400 MHz, CDCl3): deltaH 8.8 (br. s., 1 H), 8.3 (d, J=7.95 Hz, 1 H), 8.0 (m, 3 H), 7.8 (d, J=2.57 Hz, 2 H), 7.4 (m, 1 H), 7.3 (m, 5 H), 7.2 (m, 3 H), 3.5 (m, 2 H); 13C-NMR (100 MHz CDCl3): deltaC 166.6, 149.4, 144.1, 142.8, 142.6, 139.2, 137.6, 135.5, 130.9, 129.2, 128.9, 126.9, 126.3, 125.0, 123.4, 123.1, 122.4, 120.8, 120.3, 120.0, 119.8, 119.7, 110.7, 42.9; LR-ESI-MS: C24H19N4O [M+H]+ m/z found 379.25, cald 379.16.
The synthetic route of 140914-89-2 has been constantly updated, and we look forward to future research findings.
