Reaction Steps

A mixture of 4-[(3-amino-6-bromo-pyrazin-2-ylamino)-methyl]-phenol (25 mg, 0.085 mmol), 2-thiopheneboronic acid (13 mg, 0.10 mmol), Pd(PPh3)2Cl2 (2 mg, 0.0028 mmol), and NaHCO3 (21 mg, 0.25 mmol) in DME (0.5 mL) and water (0.15 mL) was put in a microwave reaction tube and reacted in a microwave reactor at 110° C. for 7 minutes. The reaction mixture was partitioned in ethyl acetate and water, and the organic layer was evaporated. The residue was purified on a C-18 reversed phase preparative HPLC eluting with Methanol/Acetonitrile containing 0.1% trifluoroacetic acid to 4-[(3-amino-6-thiophen-2-yl-pyrazin-2-ylamino)-methyl]-phenol trifluoroacetic add salt as a white solid (12 mg).
