Hydrogen Bromide → HCID 70573577, compound

Participants

Reaction Steps

A solution of 7-cyanomethyloxy-2,2-dimethyl-4-(3-trifluoromethylphenyl)chroman (5.4 g) and 10% palladium on charcoal (0.5 g) in ethanol (75 ml) was hydrogenated at atmospheric pressure. The catalyst was removed by filtration and the filtrate evaporated under reduced pressure to give an oil which was treated with ethereal hydrogen bromide to give the title compound (4 g) as a very hygroscopic non-crystalline compound.
