Abstract: A novel trifluoroacetylating agent, i.e., N-trifluoroacetylmorpholine, is described. This reagent is useful in the preparation of phenyl and heterocyclic sulfonamide compounds. Methods are therefore described for preparing sulfonamide compounds of the following structure, wherein R1 and R2 are defined herein, using N-trifluoroacetylmorpholine. The sulfonamide compounds that may be prepared as described herein include 5-chloro-thiophene-2-sulfonic acid [(1S,2R)-2-(3,5-difluoro-phenyl)-3,3,3-trifluoro-1-hydroxymethyl-propyl]-amide using N-trifluoroacetylmorpholine.

Abstract: A communications service provision support system supports multiple different types of services during a service session. The system when in use comprises a session manager which performs functions generic to each of the multiple different types of services during service sessions. For each of the multiple types of services, the session manager is arranged during a service session to generate event messages indicating at least one discrete change which has just occurred in the session-related status of individual users of the system without any historical data, and to transmit the event messages to an event handler for processing.
