A mixture of 2-bromo-6-phenylcyclohexanone (84 mg, 0.332 mmol, from preparation AAA) and 1-(3-methoxy-4-(3-methyl-1H-1,2,4-triazol-1-yl)phenyl)thiourea (87 mg, 0.332 mmol, from step 4 of preparation F) was heated in ethanol (0.55 mL) at 80° C. for 3 h. The crude reaction was diluted with EtOAc and washed with saturated sodium bicarbonate solution. The organic layer was concentrated in vacuo. The crude product was purified using preparatory TLC (60% acetone/hexanes) to give 54 mg (39% yield) of the titled compound as a white solid. LC-MS (M+H)+ 418.0. 1H NMR (400 MHz, chloroform-d) δ ppm 8.44 (s, 1 H) 7.49 (dd, J=5.41, 3.15 Hz, 2 H) 7.23-7.35 (m, 2 H) 7.12-7.21 (m, 3 H) 6.60 (dd, J=8.56, 2.27 Hz, 1H) 3.98-4.08 (m, 1 H) 3.49 (s, 3 H) 2.66-2.85 (m, 2 H) 2.46 (s, 3 H) 2.17-2.26 (m, 1 H) 1.92-2.05 (m, 1 H) 1.78-1.91 (m, 2 H).
