Related Products of 402-61-9<\/a>, These common heterocyclic compound, 402-61-9, name is 5-Methyl-1H-pyrazole-3-carboxylic acid, 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.<\/p>\n

After 16 h, the reaction mixture was diluted with Et2O (50 mL), washed with saturated aq NaHCO3 (3×50 mL) and brine (3×50 mL). The organic layer was separated, dried over MgSO4 and concentrated. Chromatography on a Biotage 40+S cartridge using 1 : 1 v\/v EtOAc\/Hexanes as the eluant afforded the title compound: 1H NMR delta 1.44 (s, 3H), 1.51 (s, 3H), 1.94 (t, J= 12.5, IH), 2.26-2.30 (m, 4H), 5.62 (m, IH), 6.58 (s, IH), 6.96 (d, J= 8.5, 2H), 7.12-7.29 (m, 5H), 7.69 (s, IH).<\/p>\n
