92%Chromat. In water; at 160℃; for 4h;Sealed tube; 2 mmol of acetylbutyric acid, 10 mmol of formamide and 40 mmol of water were placed in a 15 mL polytetrafluoroethylene-lined stainless steel reaction vessel.The sealed reaction kettle is placed in an oil bath that has been heated to a predetermined temperature (160 C). The reaction was carried out at 500 r/min for 240 min. The reaction vessel was taken out and cooled to room temperature with tap water. Add 13 mL of methanol to the reaction kettle.The yield of 6-methyl-2-piperidone was determined by GC,The conversion of acetylbutyrate was measured by HPLC. Using naphthalene as an internal standard to make a standard curve, The yield of 6-methyl-2-piperidone (m/z: 113.1) in the reaction mixture was determined by gas chromatography to be 92%. The conversion of acetobutyrate was determined by liquid chromatography to be 100%.

The solution was stirred to reflux for 18 h. When TLC showed that the reaction was complete, the solvent was evaporated and the resulting oil was purified via column chromatography on silica gel using hexanes;ethyl acetate (10:1) was used to obtain compound 4 as a yellow oil (12.86 g, yield 70%)[47]. 1H NMR (400 MHz, CDCl3): δ 1.27 (d, 3H, CH3), 1.52 (s, 9H), 1.66-1.77 (m, 2H), 1.90-1.96 (m, 2H), 2.43-2.51 (m, 2H), 4.26-4.31 (m, 1H).

YieldReaction ConditionsOperation in experiment
65% Into a stirred solution of glutarimide (15.00 g, 0.13 mol) in CH2Cl2 (100 mL) at -78 C under a nitrogen atmosphere, the Grignard reagent CH3MgBr was added into 2-methyltetrahydrofuran (3 M, 130 mL) dropwise. Then the reaction mixture was stirred at room temperature for 12 h. NaBH3CN (9.83 g, 0.16 mol) was added, followed by the slow addition of a 6N HCl solution to keep the pH at 3-4. The reaction was continued at 25 C for 5 h. After completion, the mixture was neutralized with 1 NNaOH and extracted with CH2Cl2 (5 × 100 mL). The combined organic extracts were driedover anhydrous Na2SO4 and concentrated in vacuo. The crude product was purified bycolumn chromatography on silica gel using ethyl acetate:MeOH (20:1~10:1) to obtain compound 3 as a white solid (9.75 g, yield 65%) [45,46]. 1H NMR (400 MHz, CDCl3): δ 1.20(d, 3H, CH3), 1.30-1.37 (m, 1H), 1.66-1.74 (m, 1H), 1.87-1.91 (m, 2H), 2.24-2.31 (m, 1H),2.35-2.41 (m, 1H), 3.48-3.54 (m, 1H), 5.96 (s, br, 1H).
