Synthesis of 2-Aryl- and 5-Alkyl-2-aryloxazoles from 2-Aryl-5-bromooxazoles

Abstract
2-Aryloxazoles, their 5-deuterio derivatives, and 5-alkyl-2-aryloxazoles are prepared in good yields from 2-aryl-5-bromooxazoles via halogen/metal exchange with butyllithium followed by treatment with water, methanol-O-d, or alkyl halides, respectively.
