Reaction Steps

A little at a time, 3.90 g (44.9 mmol) of manganese(IV) oxide were added to a solution of 3.00 g (11.2 mmol) of methyl 1-(3-chloropyridin-2-yl)-3-(hydroxymethyl)-1H-pyrazole-5-carboxylate in 162 mg of dichloromethane, and the mixture was stirred at 40° C. for 4 hours. After cooling to 20° C., a further 3.90 g (44.9 mmol) of manganese(IV) oxide were added, and the mixture was heated at 40° C. overnight. After cooling to 20° C., the mixture was filtered through Celite and the filtrate was freed from the solvent under reduced pressure.
