Reaction Steps

To a mixture of 3,6-dichloropyridazine (2.98 g, 20 mmol) in DMSO (10 mL) was added 1,4-dioxa-8-azaspiro[4.5]decane (3 g, 21 mmol) and DIPEA (4.18 mL, 24 mmol). The resulting mixture was heated at 80° C. for 4 h and was then poured into H2O (300 mL). The resulting solid was washed with H2O (10 mL×3) and hexane (10 mL×3) and then dried to yield 8-(6-chloropyridazin-3-yl)-1,4-dioxa-8-azaspiro[4.5]decane.
