Procedure
17 g (0.048 mol) of (S)-2-allyloxycarbonylamino-3-(4-carbamimidoylphenyl)propionic acid ethyl ester hydrochloride were treated with 400 ml of half-concentrated hydrochloric acid for 3 h at RT. The solvent was evaporated (<30° C.) and the residue was stirred with ether. Yield=15 g (95%). MS=292.2 (M+1)+.
Workup
- customThe solvent was evaporated (<30° C.)
