Participants

Reaction Steps

The product from Example 27A (3.46 g, 20 mmol) and methyl thioglycolate (1.8 mL, 20 mmol) were combined in 40 mL THF. To the solution was added 1.08 g NaOMe (20 mmol) After 1.5 h, and additional 1.08 g NaOMe was added, and then after an additional 2 h, the reaction was quenched in 5% aq. NaHCO3 and extracted with diethyl ether. The organic extracts were dried (MgSO4), evaporated, and the product was purified by silica gel column chromatography to yield 1.23 g (25%) of the title compound: 1H NMR (300 MHz, CDCl3) δ 3.92 (s, 3H), 6.20 (br s, 2H), 8.04 (d, 1H), 8.54 (d, 1H).
