HCID 22350183HCID 22350183, compoundYield 62%

Procedure

To a boiling solution of 36 ml of xylene 1.09 g (4.5 mmol) of methyl (Z)-2-azido-3-(1H-indole-5-yl)acrylate is added in small portions. The reaction mixture is refluxed till the end of the nitrogen gas formation, then concentrated and the residue is crystallized with hexane, the product is filtered and washed with hexane to yield 0.6 g (62%) of the title compound. Mp.: 183-184° C. (hexane).
