实验步骤: Dissolve commercially available 1-cyclohexyl-pyrrolidin-2-one (88.2 g, 527.9 mmol) in 2500 mL tetrahydrofuran and cool to −78° C. Add 176 mL 2 M LDA and stir for ˜5 min. Add 2-bromomethyl-1,3-dichloro-5-methoxy-benzene (95 g, 351.9 mmol) and allow the reaction to warm to room temperature. Pour the mixture into saturated ammonium chloride and extract twice with dichloromethane. Dry over sodium sulfate, filter and concentrate under vacuum to obtain a tan solid. Add hexanes and stir rapidly before filtering. Wash the filter cake several times with cold hexane to obtain 86 g (69%) of a light-tan solid: MS (m/z): 356 (M+). the reaction to warm to room temperature extract twice with dichloromethane Dry over sodium sulfate filter concentrate under vacuum to obtain a tan solid before filtering Wash the filter cake several times with cold hexane

实验步骤: An ink composition comprising 2.5 percent by weight of Tartrazine FD&C Yellow #5, a yellow dye obtained from Buffalo Color, West Patterson, N.Y., 15 percent by weight of cyclohexyl pyrrolidone (obtained from GAF Corporation, Wayne, N.J.), and 82.5 percent by weight of deionized water was prepared by mixing together the ingredients at room temperature, stirring to obtain a homogeneous solution, and filtering. An additional ink was also prepared, said ink being of the same composition as the first except that it contained 0.3 percent by weight of Carbowax M20. The Carbowax M20 was added to the ink at room temperature and the resulting mixture was stirred for about 5 minutes to obtain a homogeneous solution. by mixing together the ingredients at room temperature to obtain a homogeneous solution filtering An additional ink was also prepared the resulting mixture was stirred for about 5 minutes to obtain a homogeneous solution
