The mixture was stirred at r. t. for 24h and quenched with H2O (50mL) in an ice bath. The solution was evaporated to remove the THF and extracted with CH2Cl2 (2\u00d730mL). The organic layer was washed with saturated NaHCO3 and brine, dried over MgSO4, filtered and concentrated. The residue was purified by column chromatography using petroleum ether-EtOAc as the eluent to afford compounds 5, 6, 7, 8 and 9.<\/p>\n<p>These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 5-(Bromomethyl)-1,3-dimethyl-1H-pyrazole, its application will become more common.<\/p>\n<p>Reference:<br \/><a href=\"https:\/\/doi.org\/10.1016\/j.ejmech.2018.08.064\">Article; Chen, Duozhi; Zhang, Heng; Jing, Chenxu; He, Xiaoli; Yang, Bijuan; Cai, Jieyun; Zhou, Yunfu; Song, Xiaoming; Li, Lin; Hao, Xiaojiang; European Journal of Medicinal Chemistry; vol. 157; (2018); p. 1491 &#8211; 1499;<\/a>,<br \/><a href=\"https:\/\/en.wikipedia.org\/wiki\/Pyrazole\">Pyrazole &#8211; Wikipedia<\/a>,<br \/><a href=\"https:\/\/www.sciencedirect.com\/topics\/chemistry\/pyrazoles\">Pyrazoles &#8211; an overview | ScienceDirect Topics<\/p>\n","protected":false},"excerpt":{"rendered":"<p>These compound has a wide range of applications.
