摘要:
A process for crystallizing N.sup.2 -((S)-1-ethoxycarbonyl-3-phenylpropyl)-N.sup.6 -trifluoroacetyl-L-lysyl-L-proline using one or a mixture of at least two kinds of compound having the general formula: CR.sup.1 R.sup.2 R.sup.3 R.sup.4 as a crystallizing solvent, optionally with an auxiliary solvent which controls crystallization condition.
