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
EXAMPLE 2 t-Butyl 3-Oxo-1-piperazinecarboxylate (2) To a mixture of piperazinone 1 (1.0 g, 1.0*10-2 mole) and sieve dried THF (15 ml) is added dropwise a solution of di-tert-butyl dicarbonate (2.4 g, 1.1*10-2 mole) and sieve dried THF (5 ml). Evolution of CO2 occurs immediately and the starting material slowly dissolves. After stirring at room temperature overnight the solvent is evaporated at reduced pressure affording 2 as a beige solid which crystallized from ethyl acetate/hexane as colorless plates: 1.2 g (60%), m.p. 159-161 C.
5625-67-2 Piperazin-2-one 231360, apiperazines compound, is more and more widely used in various fields.
