Reaktionsschritte
By the method of part A of Example 3 N-(tert-butyloxycarbonyl)-N-methyl-D-alanine (2.03 g.) was condensed with 3-(4-fluorophenyl)propylamine (prepared by condensing 4-fluorobenzaldehyde with cyanoacetic acid in refluxing pyridine using piperidine as catalyst and hydrogenating the resulting β-4-fluorophenyl)acrylonitrile in ethanolic ammonia under high pressure using Raney nickel catalyst, m.r. of methanesulfonate salt 129°-131° C.; 2.49 g.), affording N2 -(tert-butyloxycarbonyl)-N2 -methyl-N-[3-(4-fluorophenyl)propyl]-D-alaninamide as a syrup (2.77g.).
