6,7-Dimethoxy-1,2,3,4-tetrahydroisoquinoline hydrochloride → alpha-(3,4-Dimethoxyphenyl)-3,4-dihydro-6,7-dimethoxy alpha-[(4-methylphenyl)thio]-2(1H)-isoquinoline tridecanenitrile

Participants

Reaction Steps

The procedure of Example 3 is repeated using 3.14 g of α-(11-bromoundecyl)-3,4-dimethoxy-α-[(4-methylphenyl)thio]benzeneacetonitrile and 2.03 g of 6,7-dimethoxy-1,2,3,4-tetrahydroisoquinoline hydrochloride. This affords 2.2 g of the desired product as a light yellow oil. MS(Hi res): m/z Calcd for C39H52N2O4S 644.3648 Found 645.3730(M+H). Calcd for C39H52N2O4S 1/2H2O: C=71.63, H=8.17, N=4.29, S=4.90 Found C=71.31, H=8.19, N=4.10, S=4.71
