Reaction Steps

5-bromo-3-(1-ethyl-1H-imidazo[4,5-c]pyridin-2-yl)pyrazin-2-amine (0.032 g, 0.10 mmol) (made in example 2), 4-dimethylaminosulphonylphenylboronic acid (0.046 g, 0.20 mmol), Pd(PPh3)2Cl2 (0.0035 g, 0.005 mmol) and K2CO3 (0.050 g, 0.36 mmol) were combined in 0.5 mL of N,N-dimethylformamide and heated to 200° C. in the SmithSynthesizer microwave for 8 minutes and then for a further 8 minutes at 250° C. The reaction mixture was concentrated in vacuo and the residue purified by HPLC to give 0.0079 g of the title compound.
