Dakin-West reaction, hydrolysis, condensation with thiocyanate derivatives, alkylation with 2-iodoacetamide and ethyl chloroacetate, and coupling with 4-pyridylmethyl chloride, ethoxymethyl chloride and benzyloxymethyl chloride. All the synthesized compounds were screened for their activity against HIV-1 (wild type) and some of them (especially Capravirine like structures) were found active.
