Participants

Reaction Steps

1-((3,5-dimethylisoxazol-4-yl)methyl)-1H-imidazol-4-amine (example 10-40a) (110 mg, 0.57 mmol), benzo[d][1,3]dioxole-5-carbonyl chloride (105 mg, 0.57 mmol), and triethylamine (90 μL, 0.69 mmol) in dichloromethane was stirred for 16 hours. The reaction was diluted with dichloromethane (30 mL) and washed consecutively with brine and water. The organics were dried over sodium sulfate and concentrated by rotary evaporation. The crude product was purified by reverse phase HPLC (Solvent system: acetonitrile/water, 10% to 100% gradient, 25 minute run) to afford N-(1-((3,5-dimethylisoxazol-4-yl)methyl)-1H-imidazol-4-yl)benzo[d][1,3]dioxole-5-carboxamide as a white crystalline solid (32 mg, 15% yield). MS M+H calculated 341.3. Found 341.3. 1H NMR (400 MHz, DMSO-d6): δ 2.08 (s, 3H), 2.41 (s, 3H), 5.02 (s, 2H), 6.07 (s, 2H), 6.95 (d, J=8.4 Hz, 1H), 7.27 (d, J=1.6 Hz, 1H), 7.54 (m, 3H), 10.6 (s, 1H). The compound had an IC50 on hT2R8 bitter receptor of 12.1 μM.
