1e yielded a mixture of 2-benzyl-4-bromo-5-(4-methylthiophenyl)pyridazin-3(2H)-one (30%) and 2-benzyl-4,5-bis-(4-methylthiophenyl)-pyridazin-3(2H)-one (3%). Although formation of the monoarylated compound is favoured only a low yield was obtained. Moreover, it is very hard to separate 2-benzyl-4-bromo-5-(4-methylthiophenyl)pyridazin-3(2H)-one from the minor compound 2-benzyl-4,5-bis-(4-methylthiophenyl)pyridazin-3(2H)-one due to similar polarity properties
