Reaction Steps
To tert-butyl 7-iodo-1,1-dimethyl-3,4-dihydro[1]benzofuro[2,3-c]pyridine-2(1H)-carboxylate P30 (0.505 g, 1.18 mmol) was added sodium tert-butoxide (341 mg, 3.55 mmol), copper(I) iodide (20 mg, 0.08 mmol), 1,2-ethanediol (132 μL, 2.38 mmol), N,N-dimethylformamide (17 mL, 210 mmol), and finally 3-Fluoro-benzenethiol (101 μL, 1.19 mmol). The reaction mixture was flushed with N2 and heated at 120° C. under N2. After 15 h, the reaction mixture was concentrated under high vacuum, the residue dissolved in 5% methanol-methylene chloride and then filtered through a celite-silica plug. The filtrate was concentrated and purified by silica chromatography (EtOAc/hexane) to afford the product as a pale yellow oil. MS m/z: 428 [M+H]+.
