In a manner analogous to that described in Example 19(i), 3.10 g of N-(benzyloxycarbonyl)-3-(4-methoxyphenyl)-L-alanine were treated with isobutyl chloroformate followed by diazomethane to give 2.83 g of benzyl [2-(4-methoxyphenyl)-l(S)-(2-diazoacetyl)ethyl]carbamate as a pale yellow solid of melting point 88°-90° C.
