Procedure

2-Chloro-N-[3-(3-morpholin-4-yl-propyl)-5-trifluoromethyl-phenyl]-nicotinamide (2.95 g) was dissolved in a small volume of IpOH. 6-amino indazole (2.75 g) and 0.53 mL of TFA were added. The reaction mixture was heated to 155° C. in an open flask for 3.5 h. After cooling to RT the residue was dissolved in 2 N HCl. The aqueous solution was extracted 2 times with CH2Cl2, basified to pH 12 by the addition of Na2CO3 and 1 N NaOH. The solution was extracted 6 times with CH2Cl2 to isolate the product. The combined 5 extractions were dried over Na2SO4, filtered and stripped. The crude product was purified by silica gel chromatography eluting with a step gradient of 3-5% MeOH:CH2Cl2 to yield the titled compound. MS: 525 (M+1) Calc'd for C27H27F3N6O2—524.5.
