3469-69-0, name is 4-Iodopyrazole, belongs to pyrazoles-derivatives compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. Application In Synthesis of 4-Iodopyrazole<\/a><\/p>\n

1-Methyl-4-iodopyrazole (18) 4-Iodopyrazole (1) (5.0 g 25.7 mmole) was dissolved in DMF (50 mL), potassium carbonate (4.26 g 30.9 mmole) was added and stirred (2 mins) before iodomethane (1.76 mL, 4.01 g 28.3 mmole) was added. The reaction was stirred rapidly at r.t. for 17 hrs. It was filtered through a Celite pad. The filtrate was evaporated to a small volume, about 10 mL, using a rotary evaporator with a high vac. pump and the water bath at 60 C. Water (120 mL) was added to the residue. The filtered solids on the Celite pad were washed with ethyl acetate (50 ml) and these washings were used to extract the product from the aqueous. The aqueous was extracted with more ethyl acetate (2*50 mL). The combined organics were washed with water (3*30 mL) and with brine; dried and evaporated to give the title compound as a solid 4.56 g, 85%. 1H-NMR (CDCl3, 500 MHz): delta 3.93 (s, 3H) 7.42 (s, 1H), 7.50 (s, 1H).<\/p>\n
