1-(4-Chlorobutyl)-1-methyl-5-methoxy-2tetralone → 6,7,8,9,10,11-Hexahydro-1-Methoxy-5-Methyl-5,10-Methano-5H-Benzocyclononen-12-One

Participants

Reaction Steps

Using a procedure analogous to that described in Example X for the preparation of 6,7,8,9,10,11-hexahydro-3-methoxy-5-methyl-5,10-methano-5H-benzocyclononen-12-one, there is obtained from 40.5 g. of 1-(4-chlorobutyl)-1-methyl-5-methoxy-2-tetralone, 21.5 g. of the title product, b.p. 130° to 135° C. (0.3 mm.). I. R. Analysis: 5.78, 7.9 μ.
