Participants

Reaction Steps

To a 250 mL flask was added 1 (3.96 g, 20 mmol), 2 (1.85 g, 20 mmol) and 50 mL anhydrous MeOH. After 800 mg (20 mmol) Na was added to the solution, yellow precipitate was observed. The resulting mixture was refluxed overnight. The yellow precipitate was collected by filtration and then dissolved in 10 mL H2O. The pH of the resulting solution was adjusted to 6.5 by adding 2 N HCl to afford a yellow precipitate, which was collected by filtration and dried over P2O5 to afford 1.21 g (37%) of 3: TLC Rf0.11 (CHCl3/MeOH 6:1); mp>300° C.; 1H NMR (DMSO-d6) δ 2.23 (s, 3 H), 3.05 (s, 2 H), 3.32 (s, 1 H), 11.92 (s, 2 H).
