| Product | HCID 43234280 | HCID 43234280 | 55% |
Reaction Steps
A solution of formaldehyde (37% w/w, 8.2 mL) was added to a solution of 4′-Hydroxy acetophenone (100 mmol), and N-methylpiperazine (110 mmol) in EtOH. Heated at reflux overnight. The solvent was evaporated on celite and the residue was purified by flash chromatography and crystallized from heptane to give the title product as white needles in 55% yield. 1H-NMR (DMSO-d6) δ 7.76 (dd, 1H), 7.74 (s, 1H), 6.81 (d, 1H), 3.69 (s, 2H), 2.47 (br, 4H), 2.46 (s, 3H), 2.35 (br, 4H), 2.17 (s, 3H).
