Procedure

The title compound was prepared as described in the final step of Example 1 from 1-(5-tert-butyl-2H-pyrazol-3-yl)-3-[4-(2-morpholin-4-yl-ethoxy)-naphthalen-1-yl]-urea (0.022 g, 0.050 mmol), and p-tolylboronic acid (0.014 g, 0.1 mmol), using copper (II) acetate (0.014 g, 0.075 mmol), pyridine (0.01 mL, 0.1 mmol), molecular sieves (4 Å activated, 0.030 g) and methylene chloride (2 mL). The title compound was obtained as a yellow-white solid (0.013 g, 50%), mp 144-146° C.; 1H NMR (DMSO) δ 1.26(s, 9H), 2.36(s, 3H), 2.53(t, 4H) 2.82(t, 2H), 3.52(t, 4H), 4.23(t, 2H), 6.32(s, 1H), 6.94(d, 1H), 7.33(d, 1H), 7.42(d, 1H), 7.54(m, 3H), 7.90(d, 1H), 8.15(d, 1H), 8.18(d, 1H), 8.82(s, 1H), 8.96(s, 1H); MS (CI) 528(M++H).
