The title compound was prepared similarly to the methods described in Example 5, using Intermediate C instead of Intermediate B and pyrazol-4-ylboronic acid instead of pyridin-4-ylboronic acid. 1H NMR (CDCl3) δ: 8.23 (broad, 2H), 7.85 (s, 1H), 4.63 (m, 1H), 4.33 (m, 1H), 3.36 (s, 3H), 1.95 (m, 1H), 1.75 (m, 1H), 1.44 (dd, 6H) and 0.87 ppm (t, 3H); LCMS: 301.2 m/z (M+H)+; ret. Time: 1.30 min (Analytical Method E).
