Synthetic Route of 50595-15-8, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 50595-15-8, name is tert-Butyl 2-hydroxyacetate. This compound has unique chemical properties. The synthetic route is as follows.

A stirred suspension of 88 mg (2.2 mmol) sodium hydride (60percent dispersion in mineral oil) in 5 ml of dry dimethylformamide at -5¡ã C. under nitrogen was treated with 264 mg (2 mmol) tert-butylglycolate. After 10 minutes 298 mg (2 mmol) of 3,6-dichloropyridazine (Aldrich D7, 320-0) was added and the solution was allowed to warm to room temperature and was stirred overnight. The volatiles were evaporated under reduced pressure and the residue was chromatographed on silica eluding with ethyl acetate/hexane (1:2) to give 210 mg of a gum that was dissolved in 20 ml of ethanol and treated with 10percent palladium on carbon (Fluka) and hydrogenated under a hydrogen atmosphere overnight. The catalyst was removed by filtration and the volatiles were evaporated under reduced pressure to give a gum that was chromatographed on silica eluding with ethyl acetate/hexane (1:2) followed by ethyl acetate to give 50 mg of a gum [M+H+MeCN]+252. The gum was dissolved in 2 ml of dichloromethane and treated with 1 ml of trifluoroacetic acid. After 10 minutes the volatiles were evaporated and the residue triturated with toluene and re-evaportated to give a gum that was further triturated with petroleum ether bp 40-60¡ã C. to give 2-(3-pyrazinyloxy)acetic acid trifluoroacetate.
