摘要

The present invention relates to salts of aryl compounds as discussed below and to methods of manufacture thereof, as well as other subject matter. More particularly, the invention relates to salts useful as intermediates for the synthesis of the cinnamanilide of formula (Y): where Ra is selected from H, OH, C1, C2, C3 or C4 alkyl; and R1 is C1, C2, C3 or C4 alkyl.
