To a mixture 1-(3-fluoro-4-hydroxyphenyl)-3-(2-(4-fluorophenyl)acetyl)thiourea (24 mg, 0.075 mmol, Compound A of Example 3), 6-chloro-9-(dicyclopropylmethyl)-8-ethyl-9H-purine (20.7 mg, 0.075 mmol, PCT Appl. WO 99/01454, U.S. Pat. No. 6,143,743, example 831, the disclosure of which is herein incorporated by reference) 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 phased preparative HPLC to give the title compound (15.3 mg, 36%) as a white solid. 1H NMR (CDCl3) δ 12.43 (m, 1H), 8.48 (m, 1H), 8.40 (m, 1H), 7.92 (m, 1H), 7.28 (m, 4H), 7.13 (m, 2H), 3.72 (s, 2H), 3.34 (m, 3H), 1.53 (m, 3H), 0.81 (m, 2H), 0.46 (m, 4H), 0.23 (m, 2H); MS(ESI+) m/z 489 (M+H)+.
