Procedure

Using similar reaction conditions as described in step-i of example-1, tert-butyl 4-(3-(3-iodo-1-tosyl-1H-pyrrolo[2,3-b]pyridin-5-yl)benzyl)piperidine-1-carboxylate (intermediate 66G) (100 mg, 0.148 mmol) was coupled with 1-phenethyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (intermediate 59) (67 mg, 0.223 mmol) using Pd(PPh3)2Cl2 (6 mg, 0.007 mmol) and sodium carbonate (40 mg, 0.372 mmol) in toluene/ethanol/water (5/2/1 ml) to afford 90 mg (84.1% yield) of the titled compound after column purification using 50% ethyl acetate in hexane as eluent. MS: m/z=659.8 (M+1) (de t-butyl).
