Hydrogen chloride-ethyl acetate → HCID 86755311, compound

Participants

Reaction Steps

10 ml of a 4N hydrogen chloride-ethyl acetate solution was added to 10 ml of a methanolic solution of 285 mg of t-butyl (S)-N-(2-hydroxy-3-phenoxypropyl)-N-[2-[4-[[2-(2-aminothiazol-4-yl)-2-hydroxyacetyl]amino]phenyl]ethyl]-carbamate at room temperature. The reaction mixture was stirred at room temperature for four hours. The solvent was evaporated off and the residue was purified by means of silica gel column chromatography (eluate: chloroform/methanol=7/1) to obtain 222 mg of (S)-4'-[2-[(2-hydroxy-3-phenoxypropyl)-amino]ethyl]-2-(2-aminothiazol-4-yl)-2-hydroxyacetanilide dihydrochloride.
