To a mixture of 1-(3-fluoro-4-hydroxyphenyl)-3-(2-(4-fluorophenyl)acetyl)thiourea (24 mg, 0.075 mmol, Compound A of Example 3), 4-chloro-7-methylthieno[3,2-d]pyrimidine (13.8 mg, 0.075 mmol, commercially available) and 1,4-diazabicyclo[2.2.2]octane (DABCO, 8.4 mg, 0.075 mmol) was added MeCN (2 mL). The reaction was stirred at RT for 4 h and concentrated in vacuo. The residue was purified by reverse phase preparative HPLC to give the title compound (11.2 mg, 31%) as a white solid. 1H NMR (CDCl3) δ 12.45 (s, 1H), 8.79 (s, 1H), 8.61 (s, 1H), 7.93 (dd, 1H, J=13.8, 2.2 Hz), 7.46 (s, 1H), 7.43 (m, 1H), 7,28 (m, 3H), 7.12 (m, 2H), 3.72 (s, 2H), 2.51 (s, 3H); MS(ESI+) m/z 471 (M+H)+.
