Reaction Steps

Step 5--Following the general procedure of EXAMPLE 50 and making non-critical variations p-methoxyphenylpiperazine is acylated with (1,3,4,5-tetrahydrobenzo[c]oxepin-1-yl)acetic acid (CXXIII, 619 mg) and the resulting amide, 1-(4-methoxyphenyl)-4-(1,3,4,5-tetrahydrobenzo[c]oxepin-1-yl)acetyl piperazine (CXXIV, 1.07 g) is reduced according to the general procedure described in EXAMPLE 50 (making non-critical variations) to give crude product. This crude material is dissolved in ether (30 ml) and methanol (3 ml) and treated with gaseous hydrochloric acid resulting in the formation of a salt. This crude salt is recrystallized from methanol/ethyl acetate to give the title compound, mp 217.0-219.0° (uncorrected, decomp).
