Reaction Steps

A suspension of N-(4,4-dimethyl-1-trifluoroacetyl-1,2,3,4-tetrahydroquinol -7-yl)-4-(3-trifluoromethyl-2-pyridyl)-piperazine-1-carboxamide (50 mg, 0.0955 mmol) and potassium carbonate (40 mg, 0.287 mmol) in methanol (5 ml) and water (5 ml) was heated at 60° C. for 4 h. After this period, the solvents were evaporated in vacuo and the residue partitioned between DCM (50 ml) and water (30 ml). The aqueous layer was re-extracted with DCM (3×50 ml) and then the combined organic layers dried (Na2SO4) and the solvents evaporated in vacuo to give the title compound as a white solid. 1H NMR (400 MHz, CDCl3) δ (ppm): 8.45 (dd, 1H), 7.90 (dd, 1H), 7.00-7.05 (m, 2H), 6.70 (d, 1H), 6.70 (d, 1H), 6.43 (dd, 1H), 6.32 (br-s, 1H), 3.60-3.65 (br, 4H), 3.20-3.30 (m, 6H), 1.65-1.70 (m, 2H), 1.26 (s, 6H). MS (ES): MH+ 434.
