Participants

Reaction Steps

2.72 g of manganese dioxide are added to a solution of 1.04 g of α-(1-ethoxymethyl-5-pyrazolyl)-2,3-dichloro-4-methoxybenzylalcohol in methylene chloride and the mixture is stirred at room temperature for 27 hours. The reaction mixture is filtered and the filtrate is condensed to an oily residue, which is then crystallized from isopropyl ether to give 0.93 g of (2,3-dichloro-4-methoxyphenyl)(1-ethoxymethyl-5-pyrazolyl)methanone.
