2-(2-氯苯氧基)丙醇基氯化物

反应条件: temp:100.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

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