Synthetic Route of 2075-46-9<\/a>,Some common heterocyclic compound, 2075-46-9, name is 4-Nitro-1H-pyrazole, molecular formula is C3H3N3O2, 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

4-Nitro-1H-pyrazole 12 (10.0 g, 88.4 mmol) was taken in CH3CN (100 mL) in a 250 mL round bottom flask under N2. To it were sequentially added iodomethane (18.8 g, 132.0 mmol) and K2C03 (30.5 g, 221.0 mmol). The reaction mixture was heated at 100C for 1 6h. The reaction mixture was then poured into ice water (100 g) and extracted with EtOAc (3 x 100 mL). The combined organic layer was dried over anhydrous Na2SO4 and concentrated under reduced pressure. The crude was further washed with n-pentane to afford 15 as a light yellow solid (10.8 g, 96% yield). ?H NMR (400 MHz, CDC13): 88.11 (s, 1H), 8.05 (s, 1H), 3.96 (s, 3H).<\/p>\n
