Moc-Val-OH - Reference Information
| Use | MOC-L-valine (S)-2-((methoxycarbonyl) amino)-3-methylbutyric acid, a key synthetic intermediate of ledipasvir, is indicated for the treatment of chronic hepatitis C Virus (HCV) infection in adults and adolescents aged 12 to <18 years. |
| preparation method | NaOH (2.91g, 0.073 mol) was dissolved in 50 mL of water, and ethanol (150 mL) was added and 6 '( 7 g , 0.036 mol ), room temperature reaction 3 h. Adjust pH to 4~5 with 5% dilute hydrochloric acid, add water 150 mL ,AcOEt ( 100mL × 3) extraction, 100mL saturated NaCl aqueous solution washing, anhydrous sodium sulfate drying, filtering, the solvent was spin-dried under reduced pressure to obtain 6.6g of crude compound MOC-L-valine. With methyl tert-butyl ether ( 35 mL) By recrystallization, MOC-L G of 1, 4-valine was obtained as a white crystalline powder in a yield of 85%. |
