                                    A convenient and selective synthesis of 6-substituted-4-hydroxy-3-methoxycarbonyl pyridazines has been developed via a diaza-Wittig reaction. The desired products substituted at the C6 position can be obtained from readily available starting materials under mild conditions. This represents an attractive new method for the synthesis of pyridazine derivatives. (C) 2012 Elsevier Ltd. All rights reserved.
