Procedure

1-benzyl-5-(2,4-dimethoxybenzyl)-3-(1-((3,5-dimethylisoxazol-4-yl)methyl)-1H-pyrazol-4-yl)-1,3,5-triazinan-2-one (example 9-6a) (44 mg, 0.09 mmol), anisole (9 mg, 0.09 mmol), and 50% trifluoroacetic acid/dichloromethane solution (1 mL) in dichloromethane (1 mL) were stirred at room temperature for 2 hours. The reaction was concentrated, quenched with saturated sodium bicarbonate (50 mL), extracted with ethyl acetate (2×, 50 mL) and washed with brine (50 mL). The combined organic extracts were dried over magnesium sulfate, filtered and, concentrated. Purification by silica column chromotography (100% to 90% dichloromethane in methanol: 30 minute gradient) afforded 1-benzyl-3-(1-((3,5-dimethylisoxazol-4-yl)methyl)-1H-pyrazol-4-yl)-1,3,5-triazinan-2-one (19 mg, 62%) as a white solid. LC/MS; [M+H] calculated for C19H22N6O2; expected 367.18. Found 367.20. The title compound was shown to inhibit hT2R08 bitter receptor and had an IC50 of 5.84 μM.
