Cyclohexene → HCID 86612999, compound

Participants

Reaction Steps

In 75 mL of ethanol was mixed 1.30 g (6.04 mmol) of 4-fluoro-N-methyl-2,6-dinitroaniline, 3.7 mL (36 mmol) of cyclohexene and 5.1 g (2.4 mmol, 40 mol %) of 10% palladium on carbon (50% water, Degussa type). The mixture was refluxed for 2.5 h and filtered into a flask containing 0.77 g (7.3 mmol) of sodium carbonate and 1.07 g (6.04 mmol) of 2-isothiocyanato-1,3,5-trimethylbenzene. The resulting slurry was refluxed for 4 h, concentrated and slurried in dichloromethane. The slurry was filtered, concentrated and purified by flash chromatography eluting with a 70% hexanes/ethyl acetate mixture to give 0.65 g (32%) of the title compound as an off-white solid.
