109-01-3, 1-Methylpiperazine is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
A 100 mL 3-necked flask was equipped with a magnetic stirrer bar, nitrogen in- and outlet and septum. The setup was thoroughly dried using a heat gun and allowed to cool to room temperature under a nitrogen flow. Then, 4-nitrobenzoyl chloride (4.64 g, 25.0 mmol) was dissolved in dry dichloromethane (50 mL) and the solution was 10 minutes in an ice-water bath. N-methylpiperazine (2.58 g, 25.8 mmol, 1.03 eq) was added drop wise over a 10 minute time interval while stirring vigorously. The resulting suspension was stirred for 1 hour at 0 C., after which triethylamine (5.01 g, 50.0 mmol, 2.0 eq) was added and stirrring was continued at r.t. for 1 h. The reaction mixture was transferred into a separatory funnel and washed with demineralized water (3¡Á50 mL). The organic layer was dried over Na2SO4, filtered over a paper filter and all volatiles were removed under reduced pressure using a rotary evaporator to give the desired product as a pale orange solid (5.77 g 23.1 mmol, 92%)., 109-01-3
The synthetic route of 109-01-3 has been constantly updated, and we look forward to future research findings.
