Hydrochloric Acid → HCID 18707120, compound

Participants

Reaction Steps

In 20 ml of ethanol was dissolved 340 mg of 2-(3,4-diethoxyphenyl)-4-(3-nonyloxycarbonyl-4-methoxymethoxyphenyl)thiazole. Thereto was added 2 ml of 10% hydrochloric acid, and the mixture was refluxed for 20 minutes. The solvent was removed by distillation. To the residue were added 40 ml of dichloromethane and 20 ml of water, and phase separation was conducted. The organic layer was washed with 15 ml of a saturated aqueous sodium chloride solution, dried and subjected to distillation to remove the solvent. The residue was recrystallized from ethanol to obtain 245 mg of 2-(3,4-diethoxyphenyl)-4-(3-nonyloxycarbonyl-4-hydroxyphenyl)thiazole as a white powder.
