摘要：

The title compounds were obtained by reaction of aminopyrazoles IV and VII with .omega.-acetophenonesulfonyl chloride (II, R = C6H5). In agreement with the general pattern of the distribution of electron density in the pyrazole nucleus, this work confirms that the position 4 of ring is the favored site of electrophilic attacks.
