Procedure

To a stirred solution of 1-(3-{2-[4-(2-methyl-5-quinolinyl)-1-piperazinyl]ethyl}phenyl)-2-imidazolidinone (E85) in THF was added methyl iodide (1 eq.), followed by sodium hydride (1.2 eq), and the reaction was stirred for 60 minutes. The mixture was loaded onto an ion-exchange cartridge (SCX-2) and eluted with methanol followed by ammonia in methanol (1M). The basic fractions were concentrated under vacuum and purified by column chromatography (SPE cartridge, Silica) using as eluent a gradient from DCM-methanol (99:1) to DCM-methanol (98:2) affording the final compound (45% yield).
