该中间体在本合成路线中的序号：(II)The condensation beta-tetralone (I) with phenyl 4-methoxybenzoate (II) by means of NaNH2 in THF gives 3,4-dihydro-1-(4-methoxybenzoyl)-2(1H)-naphthalenone (III), which is then submitted to a Grignard reaction with 4-methoxyphenylmagnesium bromide (IV) in hot THF yielding 3,4-dihydro-2-(4-methoxyphenyl)-1-naphthyl-4-methoxyphenyl ketone (V). The cleavage of one methoxy group of (V) with sodium ethylmercaptide (A) in dry DMF affords 3,4-dihydro-2-(4-methoxyphenyl)-1-naphthyl-4-hydroxyphenyl ketone (VI), which is finally condensed with N-(2-chloroethyl)pyrrolidine (VII) by means of K2CO3 in refluxing 2-butanone.
