Example 2N-((ls,4s)-4-(l,5-dimethyl-lH-pyrazole-3-carboxamido)cyclohexyl)-5-fluoro-2-(4′- hydroxy-2′-(morpholinomethyl)biphenyl-3-yloxy)nicotinamide Step (a) N-((ls,4s)-4-(l,5-dimethyl-lH-pyrazole-3-carboxamido)cyclohexyl)-5-fluoro-2- (3-iodophenoxy)nicotinamideTo a solution of l,5-dimethyl-lH-pyrazole-3-carboxylic acid (0.123 g, 0.88 mmol) in dry DMF (10 mL) was added DIPEA (0.460 mL, 2.64 mmol) followed by HATU (0.334 g, 0.88 mmol). The mixture was allowed to stir for 10 min at RT. To this mixture was added N- ((ls,4s)-4-aminocyclohexyl)-5-fluoro-2-(3-iodophenoxy Nicotinamide (0.40Og, 0.88 mmol) and the mixture stirred overnight, poured onto water and the crude product collected by filtration, dried and used in step (c) without purification.
