Related Products of 815588-93-3,Some common heterocyclic compound, 815588-93-3, name is 1-Methyl-1H-1,2,4-triazole-5-carboxylic acid, molecular formula is C4H5N3O2, 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.
[00160] To a stirring solution of 7 (300 mg, 0.97 mmol) in DCM (30 mL) were added N, iV-diisopropylethyl amine (0.44 mL, 2.42 mmol), Int-J (147 mg, 1.16 mmol), followed by HATU (442 mg, 1.10 mmol) at 0 ¡ãC and stirred at RT for 16 h. After consumption of the starting material (by TLC), the reaction mixture was concentrated under reduced pressure to give crude product, which was purified by column chromatography by 4percent MeOH/DCM toafford yellow syrup which was further purified by preparative HPLC to afford Compound F (80 mg, 19.7percent) as colorless thick syrup. H-NMR: (400 MHz, DMSO-i): delta 9.15 (s, 1H), 8.52 (t, J= 8.0 Hz, 1H), 8.08 (s, 1H), 5.19- 5.16 (m, 1H), 4.04 (s, 2H), 4.02 (s, 3H), 3.94-3.84 (m, 5H), 3.44-3.41 (m, 1H), 2.27-2.21 (m, 2H), 1.93-1.85 (m, 2H), 1.10-1.08 (m, 3H) LCMS m/z: 419 [M++l] HPLC: 96.64percent
The synthetic route of 815588-93-3 has been constantly updated, and we look forward to future research findings.
