Reaction Steps

1,4-Dioxa-8-azaspiro[4.5]-decane (200 mmol, 28.6 g, 25.6 mL) is dissolved in 160 ml of dry acetonitrile under nitrogen and treated with K2CO3 (220 mmol, 30.3 g) followed by dropwise addition over 1.5 hours of 4-(bromomethyl)-N,N-diethylbenzamide (200 mmol, 54.01 g) as a solution in 81 mL of acetonitrile. After 16 hours, the reaction mixture is poured into 250 mL of water and extracted twice with 150 mL of methylene chloride. The pooled extracts were washed with 250 mL of brine, dried over Na2SO4 and concentrated in vacuo affording 63.9 g (192 mmol, 96% yield) of the product as a yellow-orange oil.
