Process for the preparation of azacycloalkylakanoyl pseudotetrapeptides

This invention is directed to a process for preparing a pseudotetrapeptide of formula I or a salt or prodrug thereof wherein is optionally nitrogen protected azaheterocyclyl; is a single or double bond; q is 1-5; B is alkyl, cycloalkyl, cycloalkylalkyl, alkylcycloalkyl, alkylcycloalkylalkyl, aryl, aralkyl, alkylaryl, or alkylaralkyl; Q2 is H or a carboxylic acid protecting group; J is —H, alkyl, cycloalkyl, cycloalkylalkyl, alkylcycloalkyl, alkylcycloalkylalkyl, aryl, substituted aryl, aralkyl, substituted aralkyl; L is OR1, or NR1R2, where R1 and R2 are independently —H, alkyl, cycloalkyl, cycloalkylalkyl, alkylcycloalkyl, alkylcycloalkylalkyl, aryl, aralkyl, alkylaryl or alkylaralkyl; and p is 1 or 2 which comprises the coupling of two dipeptides or psuedopeptides.
