5625-67-2, Piperazin-2-one is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
5625-67-2, Piperazine -2-one( 2g, 20 mmol) is added to DCM (30 mL) ,and under the protection of argon Et3N (3.46 mL, 24 mmol) is added ,after cooling down the room temperature to 0 , add BOC anhydride (4.79g, 22mmol) in one reaction flask and raise the room temperature . After 3 h, reaction is stopped and DCM (100 mL) is added, washed with saturated NaCl solution (30 mL x 2), dried over anhydrous magnesium sulfate, concentrated, and recrystallized from DCM and petroleum ether to give a white solid 2.8 g, yield 70%.
As the paragraph descriping shows that 5625-67-2 is playing an increasingly important role.
