The synthesis of target compounds 7a-r was accomplished using the pathways illustrated in Scheme 1. The aldehyde intermediates 2a,b and 4a-c were prepared starting from 4-hydroxybenzaldehyde (1). The reaction of compound 1 with proper aminoethyl chloride in the presence of K2CO3 and KI in CH3CN afforded corresponding O-alkylated derivatives 2a,b. On the other hand, O-alkylation of compound 1 with 1-bromo-3-chloropropane gave 3-chloropropoxy analog 3. Subsequently, the reaction of appropriate cyclic amine with intermediate 3 resulted in compounds 4a-c 21c, [21], 21a and 21b.
