3-Chloro-5- { [2-oxo- 1 -( lH-pyrazolo[3 .4-&]pyridin-3-ylmethyl)-4-(trifluoromethyl)-l,2-dihydropyridin-3-yl)oxy}benzonitrile_(6.0 g, 13.46 mmol) was stirred in DMA (140 mL) until dissolved and then cooled over ice bath for 10 minutes. This solution was treated with diisopropylethylamme (4.70 mL, 26.9 mmol) and then 4-nitrophenyl chloroformate (3.26 g, 16.15 mmol) portionwise over 5 minutes. This mixture was allowed to warm to room temperature and then stirred for 30 minutes. Formation of the intermediate carbamate was monitored by queching a small aliquot of the reaction mixture with dimethylamine and monitoring by LC-MS. The reaction mixture was then recooled over an ice bath and the cooled mixture was treated with a solution of 2-[(/er/-butoxycarbonyl)amino]-N-methylethanaminium chloride (3.40 g, 16.15 mmol) and diisopropylethylamme (2.5 mL, 14.3 mmol) in DMA (35 mL). Upon completion of addition, the cooling bath was removed and the mixture stirred for 1 hour at room temperature. This mixture was partitioned between ethyl acetate (1000 mL and 500 mL) and water (500 mL). The combined extracts were further washed with water (3x 00 mL), dried over MgS04, filtered and the solvent removed by evaporation in vacuo. This residue was pre- absorbed onto silica gel (35 g) using ethyl acetate and purified by silica gel (330 g)chromatography eluting with 0-100% ethyl acetate in hexanes. The desired fractions were combined and then solvent was removed by evaporation in vacuo. The resulting residue was further purified by re-crystallizing from ethyl acetate (75 mL) to give the title compound as a white solid. lH NMR (CDCI3) delta-8.68 (d, 1H), 8.26 (d, 1H, J = 7 Hz), 7.72 (d, 1H), 7.39 (dd, 1H, J=1.5Hz), 7.30 (dd, 1H5 3=4.6 and 8Hz), 7.16 (dd, 1H, J=2Hz), 7.02 (dd, 1H, J=1.3 and 2.3 Hz), 6.46 (d, 1H, J=7 Hz), 5.18 (bs t, 1H), 5.50 (s, 2H), 3.7 (br, 2H), 3.52 (br, 2H), 3.17 (s, 3H) and 1.44 (s, 9H) ppm.
