実験手順

To a mixed solution of 13.50 kg of (R)-2-[[2-(4-aminophenyl) ethyl]amino]-1-phenylethanol monohydrochloride, 7.29 kg of 2-aminothiazol-4-yl-acetic acid, 4.46 kg of concentrated hydrochloric acid and 270 L of water, 9.73 kg of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide monohydrochloride (EDC) was added at 15° C., and the mixture was stirred for one hour. A mixed solution of 4.10 kg of sodium hydroxide and 110 L of water was dropped in the reaction solution, thereby undergoing crystallization. A generated crystal was collected by filtration and washed with water to obtain 26.2 kg of a wet cake of the β-form crystal of (R)-2-(2-aminothiazol-4-yl)-4′-[2-[(2-hydroxy-2-phenylethyl)amino]ethyl]acetanilide. This crystal was used for recrystallization as it was in the wet state.
