Procedure

1,2,3,4-Tetrahydro-1-methoxymethyl-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 2-methoxyacetyl chloride for cyclopropylcarbonyl chloride.
