the procedure described in step f a solution of 5 70 g of 1 p hydroxyphenyl 4 m methoxyphenyl 2 phenyl 1 butanone and 5 70 g of p toluenesulfonic acid in 250 ml of benzene was heated under a dean starke trap until the evolution of water ceased 21 2 hours the mixture was allowed to cool diluted with water and washed in turn with aqueous sodium bicarbonate water and a saturated solution of sodium chloride the residue which remained when the organic layer was taken to dryness was recrystallized from acetone cyclohexane there was obtained 4 37 g 82 of 1 p hydroxyphenyl 6 methoxy 2 phenyl 3 4 dihydronaphthalene m p 158 u00b0 162 u00b0 c a solution of 1 g of 1 p hydroxyphenyl 6 methoxy 2 phenyl 3 4 dihydronaphthalene in 20 ml of tetrahydrofuran and 1 ml of tertiarybutyl alcohol was added to 100 ml of ammonia redistilled from lithium to this there was added 42 mg of lithium wire the color faded very quickly after 5 to 10 minutes an additional 42 mg of lithium were added the blue color this time prevailed for 20 minutes after the addition of 1 g of solid ammonium chloride the mixture was taken.
