HCID 196102271,2,3,4-Tetrahydro-1-cyclobutyl-6,7-dimethoxyisoquinoline

Procedure

1,2,3,4-Tetrahydro-1-cyclobutyl-6,7-dimethoxyisoquinoline was prepared by a procedure analogous to that described in example 4 for 1,2,3,4-tetrahydro-1-cyclopropyl-6,7-dimethoxy- isoquinoline but substituting in the first step cyclobutylcarbonyl chloride for cyclopropyl- carbonyl chloride.
