Alkylation of pyrazolones via the mitsunobu reaction

The reaction of 3-methyl-1-phenyl-2-pyrazolin-5-one and 4-acyl derivatives thereof (R4 = COPh, 2-thienoyl, COCH2CH2Ph, COCH=CHPh) with various alcohols under 'Mitsunobu'-conditions was studied. In many cases selective O-alkylation could be achieved.
