2-methyl-2-propan-2-ylsulfanylpropanoic acid

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of ethyl 2-(isopropylthio)-2-methylpropionate (5.4 g, 30 mmol) and potassium hydroxide (5.0 g, 90 mmol) in ethanol is refluxed for 6 hours, cooled, and concentrated in vacuo to obtain a residue. The residue is diluted with water, washed with ether, acidified with hydrochloric acid, and extracted with ether. The combined organic extracts are washed sequentially with water and brine, dried over anhydrous magnesium sulfate, and concentrated in vacuo to obtain a solid. The solid is washed with chloroform and dried under reduced pressure to give the title product as a solid, mp 51.5-52.5° C. is refluxed for 6 hours cooled concentrated in vacuo to obtain a residue washed with ether extracted with ether The combined organic extracts are washed sequentially with water and brine dried over anhydrous magnesium sulfate concentrated in vacuo to obtain a solid The solid is washed with chloroform dried under reduced pressure

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.
