5625-67-2,5625-67-2, Piperazin-2-one is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
2-Piperazinone (2.5 g; 24.97 mmol) was dissolved in DCM ( 55 ml ). A solution of tert- butyloxycarbonyl anhydride (5.45g, 24.97mmol) in DCM (20 ml) was added dropwise. The reaction mixture was stirred at room temperature for 4 h. The reaction mixture was concentrated to dryness and dried under high vacuum, at room temperature. The residue containing Int. 177 (5.1 g) was used as such in the next reaction step.
As the paragraph descriping shows that 5625-67-2 is playing an increasingly important role.
