A mixture of 2-bromo-6-phenylcyclohexanone (89 mg, 0.352 mmol, from preparation AAA) and 1-(4-(4-chloro-1H-imidazol-1-yl)-3-methoxyphenyl)thiourea (99 mg, 0.352 mmol, from step 4 of preparation A) was heated in ethanol (0.60 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 42 mg (26% yield) of the titled compound as a white solid.
