Procedure

5-(1-Benzenesulfonyl-5-chloro-1H-pyrrolo[2,3-b]pyridin-3-ylmethyl)-4-chloro-thiazol-2-ylamine (592, 30 mg, 0.083 mmol, prepared as described in Example 66, Scheme 183) was combined with 6-methoxy-pyridine-3-carbaldehyde (618, 26.2 mg, 0.165 mmol) in a 2 mL microwave reaction vial. The mixture was dissolved in ethanol: acetic acid (95:5, 0.6 mL). Silica supported cyanoborohydride (1.0 mmol/g, 83 mg, 0.083 mmol) was added and the mixture was irradiated with microwave on 300 watts for 5 minutes at 100° C. The silica was separated by centrifuging and the supernatant solution was decanted. The silica residue was rinsed with ethanol (0.500 mL) and centrifuged. The solvents were combined and removed under reduced pressure to give the desired compound 619, which was used without further purification.
