실험 절차

To a solution of 8-fluoro-9-iodo-3-((1-methyl-1H-pyrazol-5-yl)methyl)-3,4,5,6-tetrahydro-4,6-methanobenzo[3,4]cyclohepta[1,2-d]imidazole-2-carboxamide (67 mg, 0.14 mmol) in piperidine (2 mL) was introduced 2-methyl-3-butyn-2-ol (68 mg, 0.81 mmol) and copper(I) iodide (2 mg, 0.01 mmol). The solution was de-oxygenated by nitrogen bubbling for five minutes, then tetrakis(triphenylphosphine)palladium(0) (9 mg, 0.01 mmol) added and bubbling continued for a further two minutes. The pressure tube was closed under an atmosphere of nitrogen and the reaction mixture warmed to 50° C. for 4 hr. After evaporation of the reaction mixture in vacuo, the residue was suspended in ethyl acetate (30 mL) and washed with saturated aqueous sodium bicarbonate (2×10 mL), water (2×10 mL) and brine (10 mL). The organic extract was dried over sodium sulfate, filtered and the filtrate adsorbed onto silica gel in vacuo. Purification of the dry-loaded material by silica gel flash column chromatography (eluent: dichloromethane containing a 0-4% gradient of 7M ammonia in methanol) furnished the title compound (47 mg, 0.11 mmol, 78%) as off-white fine crystals: 1H NMR (500 MHz, CDCl3) δ 1.64-1.72 (m, 8H), 2.43 (br. s., 1H), 2.90 (qd, J=7.93, 3.00 Hz, 2H), 3.31-3.40 (m, 1H), 3.54-3.61 (m, 1H), 3.92 (br. s., 3H), 5.49 (br. s., 1H), 5.87 (s, 2H), 6.83 (d, J=10.09 Hz, 1H), 7.42 (br. s., 1H), 8.42 (d, J=7.57 Hz, 1H); M+1=434.
