Acetic Acid → HCID 178426049, compound

Participants

Reaction Steps

Two ml of 48 percent hydrobromic acid were added with stirring to mixture of 1.38 g (5.5 mol) of 2-methoxy-3-methyl-5-(trifluoromethyl)pyridine and 6 ml of glacial acetic acid at 100° C. and the mixture was allowed to react at about 95° C. for 20 min. The mixture was then cooled and poured onto ice and the solid that formed was collected by filtration. A second crop of solid was obtained by adding more water to the filtrate. The combined solids were dried to obtain 0.40 g (40 percent of theory) of the title compound as a white powder melting at 141°-143° C. The proton nmr spectrum was consistent with the assigned structure.
