Method for crystallizing maleic acid salt of N-(1(S)-ethoxycarbonyl-3-phenylpropyl)-L-alanyl-L-proline |
| abstract |
A process for simply and easily crystallizing a maleate salt of N-(1(S)-ethoxycarbonyl-3-phenylpropyl)-L-alanyl-L-proline (enalapril) having a high quality out of an aqueous liquid, which comprises mixing an aqueous liquid having a pH of not less than 4 and containing N-(1(S)-ethoxycarbonyl-3-phenylpropyl)-L-alanyl-L-proline, maleic acid and a base with an amount of an acid sufficient to convert substantially all the base into a neutral salt. |
