Procedure

N-Bromosuccinimide (9.97 g, 0.056 mol) was added to a solution of 2-[5-(4-fluorophenyl)-3-(l-methylethyl)-1H-pyrazol-1-yl]pyrimidine (15.8 g, 0.056 mol) in DMF at 0° C. The resulting mixture was allowed to warm to room temperature over 24 hours. This was then poured into 500 mL water. The white solid which precipitated was collected by filtration and dried to yield 16.7 g of 2-[4-bromo-5-(4-fluorophenyl)-3-(1-methylethyl)-1H-pyrazol-1-yl]pyrimidine (3), mp 130°-133° C.
