Procedure

To a solution of tert-butyl 4-(4-amino-1-methyl-1H-pyrazol-5-yl)-5,6-dihydropyridine-1(2H)-carboxylate (85 mg, 0.31 mmol) in DCM (20 mL) was added DIPEA (0.5 mL, 2.87 mmol), PyBOP (0.238 g, 0.46 mmol) and 5-(tert-butoxycarbonylamino)-2-(2,6-difluorophenyl)thiazole-4-carboxylic acid (0.114 g, 0.32 mmol) and the mixture was stirred at room temperature for 18 hr. The mixture was diluted with DCM and washed with water. The organic layer was separated, dried over MgSO4 and the solvent removed under reduced pressure. Purification via silica gel column chromatography (0-75% EtOAc/isohexane) gave tert-butyl 2-(2,6-difluorophenyl)-4-(1-methyl-5-(tert-butyloxycarbonyl-1,2,3,6-tetrahydropyridin-4-yl)-1H-pyrazol-4-ylcarbamoyl)thiazol-5-ylcarbamate as a white solid (54 mg, 29%).
