Reaction Steps

To a solution of 3 g of 3-bromo-2-(diethoxymethyl)-benzo[b]furan in 80 ml of dry ether under nitrogen at −100° C. was added 17.4 ml of a 1.7 M solution of tert-butyllithium in hexanes. The solution was stirred at the low temperature for 2 h then a solution of 2.76 g of N-methoxy-N-methyl-2-fluorobenzamide in 20 ml of dry ether was added and the solution stirred at the low tempertature for 10 min. The solution was then allowed to slowly warm to 0° C., water was added and the organic layer was separated, washed with water and dried over sodium sulfate and evaporated. Gravity chromatography eluting 0 to 50% toluene in heptane afforded 0.91 g of 2-(diethoxymethyl)-3-(2-fluorobenzoyl)-benzo[b]furan as an oil, 1H-NMR (200 MHz, CDCl3) d 5.76 (CHOEt).
