Participants

Reaction Steps

To a solution of (+)-2,2-dibutyl-5-(2-quinolylmethoxy)-1,2,3,4-tetrahydro-1-naphthol (14.5 g) in ethyl acetate (145 ml) was added 3N-hydrogen chloride solution in ethyl acetate (20 ml) in one portion with vigorous stirring at ambient temperature. After stirring for 20 minutes, the precipitates were collected by filtration and washed with ethyl acetate. The pale yellow solid was recrystallized from acetonitrile to yield (+)-2,2-dibutyl-5-(2-quinolyl-methoxy)-1,2,3,4-tetrahydro-1-naphthol hydrochloride (11.605 g) as white solid.
