Application of 151230-42-1

A common heterocyclic compound, the benzoxazole compound, name is 6-Bromo-2-methylbenzo[d]oxazole,cas is 151230-42-1, mainly used in chemical industry, its synthesis route is as follows.,151230-42-1

A mixture of 1.0 mmol of 6-bromo-2-methyl-benzooxazole [151230-42-1], 2 mmol of acrylonitrile, 1.0 mmol of sodium acetate, 0.1 mmol of Pd(OAc)2 and 0.2 mmol of P(o-tolyl)3 in 3 ml of DMF under N2 atmosphere is treated at 1500C for 1 h in the microwave. The reaction is filtered through a short plug of Hyflow. The solvent of the filtarate is concentrated by evaporation. The title compound is obtained from the residue by chromatography on Varian Mega Bond Elut (Si) eluting with EtOAc to a mixture of petroleum ether/EtOAc 10:1 to afford the title compound as a mixture of cis and trans geometric isomers. Rf = 0.15 (CH2CI2-MeOH 100:2); Rt = 4.48.

As the rapid development of chemical substances, we look forward to future research findings about 151230-42-1
