The resulting salt of formula 33 is then decarboxylated to produce a dihydroisoquinolinium salt of formula 34 (step 5). For example, 3-carboxy-3-[4-(3,4-dimethoxyphenyl)-4-isopropyl-4-cyanobutyl]-6,7-dimethoxy-N-methyl-1,2,3,4-tetrahydroisoquinolinium chloride (33) is treated with Et2N, followed by POCl3, to produce 3-[4-(3,4-dimethoxyphenyl)-4-isopropyl-4-cyanobutyl]-6,7-dimethoxy-N-methyl-1,4-dihydroisoquinolinium chloride (34).
