Allyl bromide → HCID 22988177, compound

Participants

Reaction Steps

To a mixture of sodium hydride (0.33 g) in tetrahydrofuran (10 ml) was added N-[(3-chloro-5-trifluoromethyl-2-pyridyl)methyl]-2-chlorobenzenethioamide (for preparation see PCT/GB/99/00304) (3.07 g) in tetrahydrofuran (50 ml) dropwise with stirring for 20 minutes until effervescence had ceased. Allyl bromide (0.09 g) in tetrahydrofuran (5 ml) was added to the reaction mixture, and the solution was stirred overnight at room temperature. The mixture was evaporated to dryness and the residue partitioned between dichloromethane (10 ml), water (5 ml) and brine (5 ml). The organic phase was separated and the solvent and any residual water evaporated in vacuo. The residue was purified by silica gel chromatography, gradient eluting with light petroleum (b.p. 60-80° C.)/diethyl ether to give the title product.
