実験手順
A solution of 2-Fluoro-5-nitro-benzoyl chloride (CAS: 7304-32-7; Feng, Y.; Burgess, K.; Chem.Europ.J.; EN; 5; 11; 1999; 3261-3272) (0.054 g, 0.261 mmol) in dioxane (1 ml) was treated with triethylamine (0.073 ml, 0.522 mmol) and then with a solution of 1-(3-Fluoro-4-piperazin-1-yl-phenyl)-ethanone (CAS: 189763-57-3; WO9714690) (58 mg, 0.261 mmol) in dioxane (1 ml). The mixture was stirred at room temperature for 30 minutes. The solvent was removed in vacuo. The crude oil was taken in water. The aqueous layer was extracted 3 times with CH2Cl2. The combined extracts were dried over Na2SO4, filtered and the solvent was removed in vacuo. The crude gum was purified on silicagel (eluent: heptane/ethylacetate 0%-20% (10 minutes) to provide the title compound (69 mg, 68%) as a light yellow solid, MS (m/e): 390.2 (MH+, 100%)
