Reaction Steps

Methyl 2,6-difluoro-4-(3,3-dimethylbut-1-ynyl)benzoate (1.0 g, 0.004 mol) and lithium hydroxide (0.57 g, 0.012 mol) were placed in a 3:1 mixture of methanol:water (60 mL) and heated at 60° C. for 3.5 h. The reaction was cooled and concentrated in vacuo to a volume of 20 mL. The mixture was placed in an ice-water bath and acidified to pH 5 with coc. HCl. A white solid crashed out which was filtered and washed thoroughly with water. The solid was dried in the vacuum oven to give the product (0.79 g, 84%) as a solid. m/z=237.1 (M−1).
