simple and convenient one-pot synthesis of aryl alkyl ethers by the alkoxylation of arylhalides with alcohol in the presence of Triton B as a base is described. The procedure is applicable for a variety of aryl and heteroarylhalides, and yields are very good. The use of a nonmetallic base and solvent-free conditions are important features of the reaction.

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 suitable for use as active compounds in pharmaceuticals, for the treatment of cardiovascular and cerebrovascular disorders and/or disorders of the urogenital system, in particular for the treatment of erectile dysfunction.
