Procedure

3-(1-((3,5-dimethylisoxazol-4-yl)methyl)-1H-pyrazol-4-yl)imidazolidine-2,4-dione (example 10-1) (275 mg, 1 mmol), (3,4-dimethoxyphenyl)methanol (201 mg, 1.2 mmol), N,N,N,N-tetramethylazodicarboxamide (344 mg, 2 mmol) were dissolved in 2 mL anhydrous THF. Tributylphosphine (404 mg, 2 mmol) was added and the reaction mixture was placed in a microwave reactor for 5 minutes at 90° C. The reaction was filtered, concentrated and purified by HPLC (10-95% Acetonitrile/Water, 25 minutes) to afford the title compound. Yield: 25 mg, 6%. 1NMR (DMSO, 400 MHz): δ2.119 (s, 3H), 2.385 (s, 3H), 3.724 (J=6.4 d, 6H), 3.946 (s, 2H), 4.435 (s, 2H), 5.178 (s, 2H), 6.885 (m, 3H), 7.776 (s, 1H), 8.166 (s, 1H). MS M+H calculated 426.1; found 426.1. The title compound was shown to inhibit hT2R08 bitter receptor and had an IC50 of 0.06 uM.
