Procedure

To a 5° C. suspension of N-(4-bromo-2-pyrimidin-2-yl-phenyl)-2,2-dimethyl-propionamide (32.6 grams, 97.5 mmoles) in TFA (400 mL) was added 90% nitric acid (70 mL, 1.46 mmoles) over a 30 minute period. The mixture was then allowed to warm to room temperature and stir for a total of 2 hours. The crude reaction (now homogenous) was poured into ice producing a pasty mass. The mixture was diluted to 2 L total volume with water, treated with 500 mL of methanol, and vigorously stirred for 12 hours. The resulting solids were filtered, washed with copious amounts of water, then vacuum dried at 50° C. to afford the title compound (29.9 grams, 81% yield) as a tan powder.
