Carbon Tetrachloride → HCID 20570489, compound

Participants

Reaction Steps

7-Benzyloxy-2,2-dimethyl-4-(3-trifluoromethylphenyl)-2H-chromene (10.0 g) was dissolved in ethanol (100 ml) and 10% Pd/C (1 g) added. This was hydrogenated at 60° and 5 atmospheres pressure for 18 hrs. Filtration through kiesleguhr and evaporation of the solvent under reduced pressure gave an oil which solidified on addition of carbon tetrachloride. Recrystallisation from carbon tetrachloride gave the title compound (7.7 g), m.p. 63°-68° C., (analysing as compound plus 1 mole of carbon tetrachloride).
