Participants

Reaction Steps

To a solution of 1,4-dioxa-8-azaspiro[4,5]decane (9.02 g) and diisopropylethylamine (9.77 g) in ethanol (30 ml) was added 4,6-dichloropyrimidine (9.88 g), and the mixture was stirred at room temperature for 1 hour. The reaction solution was concentrated, and the residue was diluted with dichloromethane (150 ml). The mixture was washed with 0.3N sodium hydroxide solution and saturated brine, dried and concentrated, and the residue was crystallized from diethylether to give colorless crystals of 8-(6-chloropyrimidine-4-yl)-1,4-dioxa-8-azaspiro[4,5]decane (15.84 g).
