应用

3-氯-4-羟基苯甲酸甲酯是一种有机中间体，可通过一步酯化反应由3-氯-4-羟基苯甲酸制得。它广泛应用于有机合成和医药领域，可用于实验室研发和化工生产过程中。

制备

向1.0克（5.8毫摩尔）3-氯-4-羟基苯甲酸溶解于30毫升甲醇中，加入3毫升（56.3毫摩尔）硫酸，并在60℃下搅拌混合物12小时。随后将反应混合物冷却至室温，真空除去甲醇。接着，将残留物用饱和的K₂CO₃溶液和乙酸乙酯（各3×30毫升）萃取三次，干燥后过滤并在真空中浓缩。最终得到白色固体3-氯-4-羟基苯甲酸甲酯0.9克（产率83%）。经检测：ESI-MS m/z理论值186.5，实测值187.5（M+1）+；保留时间1.17分钟（总运行时间3分钟）。

  A novel series of benzoic acid derivatives as VLA-4 antagonists were synthesized. Optimization, focusing on activity and lipophilicity needed for cell permeability, resulted in the identification of 15b and 15e with good activity (IC50=1.6 nM each) and moderate lipophilicity (Log D=2.0, 1.8). Furthermore, 15e demonstrated efficacy in murine asthma model by an oral dose of 30 mg/kg.
