Versuchsvorschrift

A mixture of 7-bromo-9-(4-fluorophenyl)-1,4-dioxaspiro[4.5]decan-8-on (50 mg, 0.177 mmol, preparation AAC) and 1-(4-(4-chloro-1H-imidazol-1-yl)-3-methoxyphenyl)thiourea (91 mg, 0.276 mmol, from step 4 of preparation A) was heated in ethanol (0.25 mL) at 80° C. for 45 min. 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 (50% acetone/hexanes) to give 54 mg (57% yield) of the titled compound as a white solid.
