dealkylation. The yield of benzoylation of p-xylene 4 with benzoic acid in the presence of 5 mol% C4F9SO3H to give 2,5-dimethylbenzophenone 5 could significantly be improved from 14% to 90% by continuous removal of water formed during the acylation. Also in the preparation of alkylanthraquinones 7 by reaction of alkylbenzenes with phthalic anhydride, water removal is the decisive factor to obtain satisfactory

Compounds of formula (I), and salts and pro-drugs thereof: Formula (I) wherein for example R
1
is optionally substituted aryl or heteroaryl; Y is a linking group selected from, for example, a direct bond, and a (substituted) alkyl chain; R
2
is an optionally substituted aryl, an optionally substituted cycloalkyl or an optionally substituted heterocyclic group; are described. Processes to make such compounds and their use as DGAT inhibitors, for example in the treatment of obesity, are also described.
The present invention relates to substituted sulfonamide compounds of the general formula (I), wherein P is sulfonamide or amide-substituted sulfonic acid, which compounds are potentially useful for the prophylaxis and treatment of medical conditions relating to obesity, type II diabetes and/or disorders of the central nervous system.
