    1 is alkyl, cycloalkyl, aralkyl, aryl, etc. which may be substituted; X is -CO-, or -SO
    2 ; R
    2 is H, alkyl, or R
    2 and Y are linked to give ring-forming group; Y is alkylene which may be replaced; R
    3 is H, or alkyl; R
    4 is alkyl; R
    5 is H or alkyl; R
    6 is alkyl or phenyl which may be replaced).
    EXAMPLE: N-(1-Methyl-1-phenylethyl)-2-benzoylacetamide.
