Yield:51785-82-1 96%
Reaction Conditions:
with water;sodium hydroxide in tetrahydrofuran at 20;
Steps:
1.3
The compound (3) (1 2 g, 40 mmol) was mixed with tetrahydrofuran. Sodium hydroxide (6.40 g, 1 60 mmol) aqueous solution was added to the mixture solution. The resulting mixture was agitated at room temperature overnight and concentrated. 1 N HCI was added to adjust the pH to 1 .0. The aqueous layer was extracted with ethyl acetate three times. The whole organic layer was dried with anhydrous magnesium sulfate and concentrated to obtain the compound (4) (yield 96%) as white solid. LC-MS (ESI) : calcd for C12H20N2O5 272.1 , found m/z 273.1 (M + H+).
