Procedure
(RS)-N-(3-Methylphenylcarbamo-yl)valine may be prepared in a manner similar to that described in Example 35 for the preparation of (RS)-N-(3-methylphenylcarbamoyl)phenylglycine, but starting with (RS)-valine (4.7 g), sodium hydrogen carbonate (3.36 g) and 3-methylphenyl isocyanate (5.14 cc). (RS)-N-(3-Methylphenylcarbamoyl)valine (6.6 g), m.p. 170° C., is thereby obtained.
