Related Products of 42027-81-6<\/a>, A common heterocyclic compound, 42027-81-6, name is 2-(4-Nitro-1H-pyrazol-1-yl)ethanol, molecular formula is C5H7N3O3, 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

To a stirred solution of 2-(4-nitro-1H-pyrazol-1-yl)ethanol 17 (2.0 g, 1.23 mmol) in EtOH (25 mL), 0.40 g of Pd(OH)2 added and then stirred reaction under H2 gas atm for 1 4h. After the completion of reaction (TLC monitoring) the reaction mixture was filtered through celite bed, washed with MeOH, concentrated the solvent and the crude compound was purified by triturating with ether and pentane to give 2-(4-amino-1H- pyrazol-1-yl)ethanol precursor-07 as brown solid (1.30 g, 81% yield). MS: 128.07 (M+H).<\/p>\n

The synthetic route of 42027-81-6 has been constantly updated, and we look forward to future research findings.<\/p>\n
