Reaction Steps

A mixture of 6-quinoxalinecarboxaldehyde (0.62 g, 3.92 mmol, prepared as described in Photochem. Photobiol. 1991, 54, 7), (1,3-dioxolan-2-ylmethyl)triphenylphosphonium bromide (2.50 g, 5.82 mmol), and TDA-1 (1.20 mL, 3.75 mmol) in dichloromethane (20 mL) and sat. aq. K2CO3 (20 mL) was heated to reflux for 4 h. The layers were separated and the aqueous layer was extracted with dichloromethane (2×20 mL). The combined organic layers were washed with water (50 mL) and brine (50 mL), dried (Na2SO4), and concentrated. THF (10 mL) and 10% HCl (10 mL) were added and the mixture was stirred for 1 h at rt. The mixture was cooled to 0° C., the precipitated solids were removed by filtration, washed with water and dried in vacuo to give 0.47 g (65%) of the title compound as a tan solid. MS 185 (M+H)+.
