实验步骤: The procedure as described in Example 4a) was repeated with phenol (48 mmol) and 3-o-tolylpropanoyl chloride (55 mmol). The crude product (12.4 g, 97%) was short path distilled at 127-129° C./0.05 mbar to yield 10.6 g (93%) of product as a colourless, semicrystalline oil. distilled at 127-129° C./0.05 mbar

实验步骤: Toluene (20 ml) and thionyl chloride (1 ml) were added to commercially available 3-(2-methylphenyl)propanoic acid (80 mg), and the mixture was heated at 100° C. for one hr. The solvent was removed by distillation, and 3-(2-methylphenyl)propanoyl isothiocyanate was prepared using the resultant 3-(2-methylphenyl)propanoyl chloride as a starting compound according to the description of the literature. 4-[(6,7-Dimethoxy-4-quinolyl)oxy]-3-fluoroaniline (50 mg) was dissolved in toluene (5 ml) and ethanol (1 ml) to prepare a solution. A solution of 3-(2-methylphenyl)propanoyl isothiocyanate in ethanol (1 ml) was then added to the solution, and the mixture was stirred at room temperature for 2 hr. The reaction solution was concentrated, and the residue was purified by chromatography on silica gel using chloroform/acetone for development to give the title compound (45 mg, yield 54%). The solvent was removed by distillation, and 3-(2-methylphenyl)propanoyl isothiocyanate was prepared The reaction solution was concentrated the residue was purified by chromatography on silica gel

实验步骤: To a mixture of (3-chloro-5-trifluoromethyl-2-pyridyl)methylamine hydrochloride (1 mmol, 0.247 g) in tetrahydrofuran (5 ml) was added triethylamine (2 mmol, 0.202 g) at room temperature and the mixture was stirred at room temperature for 1 hour. The mixture was filtered and the filtrate added to a solution of 3-(2-tolyl)propionyl chloride (1.1 mmol, 0.2 g) in tetrahydrofuran (5 ml) at room temperature. After 4 hours stirring at room temperature the solvent was evaporated and the residue washed with water. The solid was filtered and washed with diethyl ether/light petroleum (1:20) to give the title product, m.p. 152-3° C. The mixture was filtered After 4 hours stirring at room temperature the solvent was evaporated the residue washed with water The solid was filtered washed with diethyl ether/light petroleum (1:20)
