BROMINATION OF 4-ARYL-3,5-DIALKOXYCARBONYL-2,6-DIMETHYL-1,4-DIHYDROPYRIDINES

4-Aryl-3,5-dialkoxycarbonyl-2,6-dimethyl-1,4-dihydropyridines are brominated by N-bromosuccinimide in methanol at room temperature at the methyl groups at positions 2 and 6 to form mono-, di-, tri-, and tetrabromo derivatives.When the N-unsubstituted brom
