Reaction Steps
Allomaltol (600 mg; 4.76 mmol) was weighed out into a round bottom flask (100 ml) containing a stir-bar. The contents were diluted with anhydrous THF (˜20 ml) and stirred (˜5 min) to afford a solution. Next, trimethyl amine (833 μl; 6.33 mmol; 1.33 equiv.) was added drop-wise and the contents stirred (˜5 min). Acetic anhydride (641 μl; 5.00 mmol) was then added drop-wise, capped and stirred at room temperature. The reaction was monitored via silica gel TLC. Once complete, the reaction mixture was concentrated under reduced pressure and the contents purified by silica gel chromatography to afford 650 mg product (3.87 mmol; 81% yield). This compound was found to have an EC50 of 106 μM. 1H NMR (DMSO-d6) δ 8.39 (s, 1H; 2-H); 6.36 (s, 1H; 5-H); 2.30 (s, 3H); 2.24 (s, 3H).
