Reaction Steps

A 2.5 ml glass microwave reaction vessel was charged with 3-(7-chlorothieno[2,3-d]pyridazin-2-yl)-N-cyclopropyl-4-methylbenzamide: (0.020 g, 0.058 mmol), acetonitrile (1 ml), morpholine (0.015 g, 0.17 mmol). The reaction mixture was heated in a Smith Synthesizer microwave reactor (Personal Chemistry, Inc., Upssala, Sweden) at 150° C. for 50 min. The solvent was evaporated under reduced pressure and the crude product was adsorbed onto a plug of silica gel and chromatographed through a Redi-Sep pre-packed silica gel column (12 g), eluting with a gradient of 5% to 95% MeOH in DCM to provide N-cyclopropyl-4-methyl-3-(7-morpholinothieno[2,3-d]pyridazin-2-yl)benzamide (0.016 g) MS (ES+): 395 (M+H)+.
