with sulfuric acid in water at 100; for 10 h;
Steps:
2 Preparation of 2-methylcyclopentanone
Methyl 1-methyl-2-oxocyclopentanecarboxylate (200 g, 1.3 mol), water (1.5 L), concentrated sulfuric acid (7.5 mL, 0.13 mol),After the addition, the temperature was raised to 100 ° C for 10 hours.The system is cooled to room temperature,The organic phase was combined and washed with 5% sodium hydrogencarbonate and saturated brine.Drying over anhydrous sodium sulfate, distilling off the solvent and distilling under reduced pressure to give 2-methylcyclopentanone 120 g.The yield was 95%.
