INTERMEDIATES FOR PRODUCING SUBSTITUTED INDOLES AS PHOSPHODIESTERASE TYPE IV INHIBITORS

摘要

Disclosed are compounds of the formulae (see fig. IV) and (see fig. V) (wherein R13 and R14 are each independently H or CH3O, and R5 is SO2NR8R12 in which R8 and R12 are each independently H or (C1-C6)alkyl or R8 and R12 together with N to which they are attached, from a pyrrolidine or piperidine ring) useful as intermediates for producing substituted indoles as phosphodiesterase type IV inhibitors.
