Reaction Steps

4-Methanesulfonyloxy-cyclohexanecarboxylic acid ethyl ester (AOKChem Co., Ltd; 689 mg; 2.75 mmol; 1.04 eq.) in DMF (5 mL) was added in one portion to a suspension of 2-[3-(1-methyl-1H-pyrazol-4-yl)phenyl]-5-(1H-pyrazol-4-yl)pyrimidine (example 3, 104 mg; 0.34 mmol; 1.0 eq.) and cesium carbonate (2.35 g; 7.21 mmol; 2.7 eq.) in DMF (10 mL). The reaction mixture was heated in MW at 120° C. for 35 min. It was then poured into water and filtered. The resulting solid was triturated with ACN to give the title compound as a yellow solid (264 mg, 17%). 1H NMR (300 MHz, DMSO-d6) δ 9.16 (s, 2H), 8.57-8.46 (m, 2H), 8.26 (s, 1H), 8.24-8.18 (m, 1H), 8.13 (s, 1H), 7.92 (s, 1H), 7.77-7.66 (m, 1H), 7.51 (t, J=7.8 Hz, 1H), 4.32-3.99 (m, 3H), 3.89 (s, 3H), 2.48-2.34 (m, 1H), 2.23-1.48 (m, 8H), 1.27-1.14 (m, 3H). MS (ESI+): 457.3.
