To a suspension of 2,4-dichloro-6-methyl-7-[(4-methylphenyl)sulfonyl]-7H-pyrrolo[2,3-d]pyrimidine (500 mg, 1.40 mmol) and 2-amino-6-fluorobenzoic acid (218 mg, 1.40 mmol) in isopropanol (15 mL) was added diisopropylethylamine (907 mg, 7.02 mmol) and the mixture was heated at 85° C. for ˜72 h. The reaction was diluted with EtOAc (100 ml) and washed with a solution of 1N HCl, a saturated solution of sodium bicarbonate and a saturated solution of NaCl. Solid began to crash out on addition of brine. Ether was added to force everything out of solution and also water was added to ensure NaCl was all in solution. The solids were filtered and dried under reduced pressure to afford 2-({2-chloro-6-methyl-7-[(4-methylphenyl)sulfonyl]-7H-pyrrolo[2,3-d]pyrimidin-4-yl}amino)-6-fluorobenzoic acid (439 mg, 0.924 mmol) as a pale yellow solid. ESIMS (M+H)+=475.
