実験手順

An acetonitrile (10 ml) solution of copper (II) sulfate (0.52 g, 3.26 mmol), copper (I) oxide (0.47 g, 3.26 mmol) and copper (II) nitrate hemipentahydrate (0.76 g, 3.26 mmol) was stirred at −30° C., and added with tert-butyl nitrite (0.41 g, 3.97 mmol) and then an acetonitrile (3 ml) solution of 3-(2-amino-4-chloro-6-fluoro-3-methoxyphenyl)-1-methyl-6-trifluoromethyl-2,4(1H, 3H)-pyrimidinedione (0.94 g, 2.56 mmol). After stirred for 16 hr (−30° C. to room temperature), the mixture was poured into cold 5% hydrochloric acid (30 ml) and then extracted with ethyl acetate (20 ml×3). The organic phase was washed with brine and dried over Na2SO4. Preparative TLC was used for purification (silica gel plates, 2000 microns, ether). Yield: 0.16 g, 0.44 mmol.
