Procedure

In a manner analogous to that described in the last paragraph of Example A, starting from the benzylamine salt of (1R)-1-[(N-benzyloxycarbonyl-L-alanyl)amino]-ethylphosphonic acid there was obtained (1R)-1-(L-alanylamino)-ethylphosphonic acid of melting point 295°-296° C (decomposition); [α]D20 = -45.6° (c = 1% in water).
