Методика

To a solution of 1-(cyclohexyl(methyl)amino)propan-2-yl 2,4,6-trimethylbenzoate (0.30 g, 0.946 mmol) in DCE (5 mL), methyl iodide (0.12 mL, 1.892 mmol) was added. The resultant reaction mixture was stirred at rt for 16 hours. The reaction mixture was diluted with DCM and concentrated to dryness. The crude product was subjected to column chromatography to obtain N,N-dimethyl-N-[2-((2,4,6-trimethylbenzoyl)oxy)propyl]cyclohexanaminium iodide. Yield: 0.109 g (25%). 1H NMR (400 MHz, CDCl3) δ 6.86 (s, 2 H), 5.70-5.67 (m, 1 H), 4.52-4.48 (d, J=14 Hz, 1 H), 3.83-3.77 (m, 1 H), 3.70-3.64 (m, 1 H), 3.34 (s, 3 H), 3.28 (s, 3 H), 2.29-2.01 (m, 10 H), 2.01-1.98 (m, 1 H), 1.84 (m, 1 H), 1.64-1.62 (d, J=6 Hz, 4 H), 1.47-1.38 (m, 4 H), 1.13-1.08 (m, 2 H).
