Diethyl Ether → 1-Naphthol

참여 물질

반응 단계

Duloxetine is acid labile, and acid hydrolysis of its ether linkage results in a thienyl alcohol and 1-naphthol. 50% of a dosage is hydrolyzed to 1-naphthol within one hour at a pH of 1.0, which is achieved under fasting conditions. At a pH of 2.0, 10% of the dosage degrades to 1-Naphthol in one hour and at a pH of 4.0, 10% degradation would take up to 63 hours. The reaction scheme showing the conversion of duloxetine to 1-naphthol and its thienyl derivative is shown below.
