129779-30-2, (3R,5S)-rel-tert-Butyl 3,5-dimethylpiperazine-1-carboxylate is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Part B: 1,1-Dimethylethyl (3R,5S)-3,4,5-trimethyl-1-piperazinecarboxylate. To a solution of 1 ,1-dimethylethyl (3R,5S)-3,5-dimethyl-1-piperazinecarboxylate (2.04 g,9.5 mmol) in dichloromethane (25 ml.) at 0 0C was added formaldehyde (1.075 ml_, 37% water solution, 14.3 mmol) followed by sodium triacetoxyborohydride (2.628 g, 12.4 mmol). The reaction mixture was allowed to warm to room temperature and stirred for 2 h before being diluted with dichloromethane and washed with 1 N NaOH solution. The organics were then washed with brine, dried (MgSO4) and evaporated to yield 1 ,1- dimethylethyl (3R,5S)-3,4,5-trimethyl-1-piperazinecarboxylate (2.06 g, 95%). LCMS: (M+H)+: 229.2.
129779-30-2, 129779-30-2 (3R,5S)-rel-tert-Butyl 3,5-dimethylpiperazine-1-carboxylate 10822535, apiperazines compound, is more and more widely used in various fields.
