YieldReaction ConditionsOperation in experiment
43% at 105℃; for 3.5h;Inert atmosphere; To a flame dried round bottom flask 0.5 g (3.6 mmol) of l-(2-hydroxyethyl)-lW- pyrrole-2,5-dione and 0.7 g (4.0 mmol) of methanesulfonic anhydride was added. The flask was evacuated and refilled with nitrogen. The flask was heated to 105C and stirred for 3.5 hr. The reaction was cooled to room temperature and dissolved in ethyl acetate (5 mL). The solution was taken up into a separatory funnel and washed four times with a saturated solution of sodium carbonate (40 mL). The aqueous layers were collected and washed with ethyl acetate (50 mL). The organic layers were combined and dried with MgS04 and concentrated in vacuo. The product was recrystallized from t-butyl methyl ether to yield 43 % (0.347 g, 1.58 mmol) of 2-(2,5-dioxo-2,5-dihydro-lH-pyrrol- l-yl)ethyl methanesulfonate.XH NMR (400 MHz, CD3CI) 6.78 (s, 2H), 4.41 (t, J = 5.23, 2H), 3.90 (t, J = 5.23, 2H), 3.04 (s, 3H)
