Reaction Steps

Following the general method of example 37, the benzaldehyde imine of benzylamine was alkylated with tert-butoxycarbonyloxy-benzyl chloride using lithium hexamethyldisilizane as a base at low temperature (−78° C.) in THF as solvent. Following the usual work up, the racemic amine was coupled to the carboxylic acid of example 2, to give after removal of the Boc group and purification by preparative C18 reversed-phase HPLC, the title compound of example 39.
