Procedure

1-(4-methoxybenzyl)-3-methyl-1H-indazol-5-amine (51 mg, 0.34 mmol) from step 2 of this example, 2-{(1S,2R)-2-[1-(5-chloropyrimidin-2-yl)piperidin-4-yl]cyclopropyl}ethyl 4-methylbenzenesulfonate from step 1 of Example 5 (75 mg, 0.17 mmol) and potassium iodide (3 mg, 0.017 mmol) combined and the solids slurried in acetonitrile. The slurry was reacted in the microwave with stirring for 80 minutes at 110° C. using normal power. The mixture was cooled to RT, diluted with 4:1 water:saturated sodium bicarbonate (40 ml), extracted with EtOAc (3×40 ml), the organic fractions combined, washed with brine, dried over Na2SO4, filtered and the volatiles removed in vacuum. The product was purified by chromatography on SiO2 eluting with 10% acetone:DCM to give the titled compound.
