Date Mar. 27, 1997A process for preparing a compound having formula (11), comprises oxidative cyclization of a tertiary amine having formula (12), wherein X1 is a removable functionality, X2 is hydrogen or a group as defined above for X1, and R1 is selected from hydrogen and alkyl, aryl, alkaryl and aralkyl groups having up to 20 carbon atoms, and R2 and R3 are independently selected from hydrogen and alkyl, aryl, alkaryl, aralkyl and acyl groups having up to 20 carbon atoms. Novel compounds are both used and produced by that process.
