To a solution of 2-[4-(2-bromoethoxy)phenoxy][1,3]thiazolo[4,5-b]pyridine (131 mg, 0.37 mmol) and 2-(piperidin-4-yloxy)-pyrimidine (80 mg, 0.45 mmol, 1.2 equiv.) in CH3CN (1.9 mL) was added N,N-diisopropylethylamine (97 μL, 0.56 mmol, 1.5 equiv.). The resulting solution was allowed to stir at 70° C. for 18 h. The solution was then cooled to rt, filtered and purified using preparative reverse phase HPLC to afford the desired product as a yellow-brown solid (64 mg, 38%). 1H NMR (600 MHz, CDCl3): 8.58-8.54 (m, 1H), 8.52-8.48 (m, 2H), 8.01-7.96 (m, 1H), 7.34-7.30 (m, 2H), 7.18 (dd, J=6.7, 4.8, 1H), 6.96 (d, J=8.1, 2H), 6.92-6.87 (m, 1H), 5.14-5.04 (m, 1H), 4.14 (t, J=5.6, 2H), 2.96-2.88 (m, 2H), 2.86 (t, J=5.5, 2H), 2.56-2.46 (m, 2H), 2.16-2.04 (m, 2H), 2.01-1.90 (m, 2H). MS (ESI): mass calcd. for C23H23N5O3S, 449.15; m/z found, 450.1 [M+H]+.
