microwave irradn. allows the title reaction to be realized in a short time in the presence of KOH, KOBu-tert, or KF-Al2O3 catalyst with or without the phase transfer catalyst aliquat. the reaction was carried out in multimode and monomode ovens; the latter appears to be better as it can give the same yield with lower power.
