Bayer Aktiengesellschaft, Jerrie L Chiu, March 26, 2002: US06362178 (45 worldwide citation)

The 2-phenyl-substituted imidazotriazinones having short, unbranched alkyl radicals in the 9-position are prepared from the corresponding 2-phenyl-imidazotriazinones by chlorosulphonation and subsequent reaction with the amines. The compounds inhibit cGMP-metabolizing phosphodiesterases and are suit ...
