A new synthetic route of C8H7ClN4

Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 943541-20-6.

Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 943541-20-6, name is 3-Chloro-6-(1-methyl-1H-pyrazol-4-yl)pyridazine, This compound has unique chemical properties. The synthetic route is as follows., SDS of cas: 943541-20-6

Quinazolin-6-yl-acetic acid hydrazide (0.032 g, 0.158 mmol) and 3-chloro-6-(l- methyl-lH-pyrazol-4-yl)-pyridazine (0.031 g, 0.158 mmol) were heated to 165C in 5 butanol (2 mL) for five hours. The reaction was cooled to room temperature, evaporated in vacuo and purified via silica gel column chromatography eluting with 5% methanol in dichloromethane to give 0.0031g (7%) of 6-[6-( 1 -methyl- IH- pyrazol^-yO-tl^^triazolo^.S-blpyridazin-S-ylmethyll-quinazoline. 1H NMR (400 MHz, CD3OD) 5 8.45 (s, IH), 8.29 (s, IH), 8.06 (d, 2H, J=9.6Hz), 7.60 (d, 2H, J=9.6Hz), 7.55 (m, IH), 7.17 (d, IH, J==8.0Hz), 6.08 (s, IH), 4.58 (m, 2H), 3.89 (s, 3H). Mass spectrum (LCMS, ESI pos.): Calcd for Ci8H)4N8; found: 343.3 (M+H).

Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 943541-20-6.
