Acetic Acid → HCID 66743409, compound

Participants

Reaction Steps

To a mixture of 50% dimethyl amine (0.4 mL), acetic acid (0.4 mL) and 38% formaldehyde (0.4 mL) were added, after which Intermediate 1 (0.4 g, 2.232 mmol) was added. The reaction mixture was refluxed for 10 min and then held for 20 min at 90° C. Reaction mixture was cooled to room temperature and diluted with water (25 mL). Two layers were separated. The aqueous layer was extracted with ethyl acetate (2×25 mL). The combined organic layers were washed with water (25 mL), dried (Na2SO4) and filtered. The filtrate was evaporated to give a crude product which was recrystallised from acetonitrile to give 97 mg of the product as a white solid; 1H NMR (δ ppm, 300 MHz, DMSO-d6) 2.08 (s, 6H), 3.23 (s, 3H), 3.30 (s, 2H), 3.69 (s, 3H), 7.13 (s, 1H), 11.93 (br s, 1H); APCI-MS (m/z) 237.00 (M+H)+.
