Reaction Steps
A mixture of 6-bromo-4-isopropoxy-quinazoline (17.9 mg, 0.067 mmol), potassium carbonate (0.13 mmol), tetrakis(triphenylphosphine) palladium (10 mg) and 3-thiophenyl boronic acid (0.08 mmol) in DME (1 ml) and water (0.5 ml) was heated to 50° C. for 30 minutes. The reaction mixture was filtered through a 0.45 micron filter and diluted with ethyl acetate (2 ml). The organic layer was washed with water (1 ml), separated, and concentrated in vacuo. The residue was purified by passage through a pre-packed silica gel column, eluting with ethyl acetate. The solvents were concentrated in vacuo to provide the desired product as a white solid (10 mg, yield: 55%). The resulting compound was characterized as follows: MS (m/z) 271.09 [M+H]+; HPLC Rt=1.83 minutes (Method A).
