Yield:75172-11-1 80%
Reaction Conditions:
with hydrogenchloride in water; for 6 h;Reflux;
Steps:
Synthesis of (S)-3-mercapto-2-methyl-propionic acid
The compound 3a-(S) (115.64 mg, 0.5 mmol) was suspended in 10 mL 2N HCl solution and the reaction mixture was heated to reflux at 120 °C for 6 h. After 6h the reaction mixture was cooled and extracted with EtOAc (3 X 20 mL) and the combined organic extracts were dried over Na2SO4. Concentrated in vacuo, purified over silica gel by column chromatography to afford the product 4.
