実験手順

A mixture of tert-butyl N-[2-bromo-4-[[5-[(2S,5R,6R)-5-(tert-butoxycarbonylamino)-6-fluoro-oxepan-2-yl]-1-methyl-pyrazol-4-yl]carbamoyl]thiazol-5-yl]carbamate (100 mg, 0.16 mmol, intermediate 88), 3-fluoro-4-tri-n-butylstannyl pyridine (93 mg, 0.24 mmol), tetrakis(triphenylphosphine)palladium(0) (9.3 mg, 0.008 mmol), copper (I) iodide (9 mg, 0.047 mmol) and lithium chloride (21 mg, 0.48 mmol) in dioxane (1.5 mL) was degassed by bubbling nitrogen gas through it for 5 min. The mixture was heated at 135° C. under microwave irradiation for 45 min. After cooling to room temperature, more 3-fluoro-4-tri-n-butylstannyl pyridine (93 mg, 0.24 mmol), tetrakis(triphenylphosphine)palladium(0) (9.3 mg, 0.008 mmol), copper (I) iodide (9 mg, 0.047 mmol) and lithium chloride (21 mg, 0.48 mmol) were added and the mixture was degassed by bubbling nitrogen gas through it for 5 min. The mixture was heated at 135° C. for 45 min, cooled to room temperature, filtered through celite and the filtrate concentrated under reduced pressure. Purification via silica gel column chromatography (0-80% EtOAc/isohexane) gave tert-butyl N-[4-[[5-[(2S,5R,6R)-5-(tert-butoxycarbonylamino)-6-fluoro-oxepan-2-yl]-1-methyl-pyrazol-4-yl]carbamoyl]-2-(3-fluoro-4-pyridyl)thiazol-5-yl]carbamate as a pale brown solid. This solid was stirred in a solution of HCl (4.0 M in dioxane, 3 mL) and MeOH (0.5 mL) at room temperature for 18 hr. The solvents were removed under reduced pressure. Purification via preparative HPLC gave 182 as the formate salt as a pale pink solid (26 mg, 33%). 1H NMR (400 MHz, d6-DMSO) δ 9.27 (s, 1H), 8.43 (d, J=2.8 Hz, 1H), 8.28-8.23 (m, 1H), 8.00 (s, 1H), 7.78-7.72 (m, 1H), 7.47 (s, 1H), 7.42 (br s, 2H), 4.78-4.58 (m, 2H), 3.99-3.85 (m, 1H), 3.79-3.67 (m, 1H), 3.49 (s, 3H), 3.17-3.02 (m, 1H), 1.90-1.80 (m, 1H), 1.67-1.51 (m, 2H), 1.41 (d, J=13.1 Hz, 1H). Alkyl NH2 not observed. LCMS (ES+) m/z 450 (M+1).
