Reaction Steps
A mixture of 1-methyl piperazine (0.55 mL, 5.0 mmol), potassium carbonate (3.49 g, 25 mmol) and chloroacetonitrile (0.34 mL, 5.6 mmol) in acetonitrile (3 mL) was stirred at room temperature 8 h. The mixture was diluted with diethyl ether and filtered and concentrated to yield the title compound as yellow crystals (536.6 mg, 77% yield). 1H NMR (500 MHz, CDCl3) δ: 3.50 (s, 2H), 2.66 (t, 4H, J=4.58), 2.52 (bs, 4H), 2.33 (s, 3H).
