Procedure
Using the procedure of Example 1, (2,4-dioxo-5-methyl-1-n-propyl-3-imidazolidinyl)methanol is reacted with the acid chloride of 2-(4-chlorophenylamino)-3-methylbutanoic acid to give (2,4-dioxo-5-methyl-1-n-propyl-3-imidazolidinyl)methyl 2-(4-chlorophenylamino)-3-methylbutanoate (A'; R is carbonyl, R' is ethylidene, R1 =R4 =R5 is hydrogen, R2 is p-chlorophenyl, R3 is isopropyl, R6 is n-propyl).
