129799-15-1, Methyl 1-Boc-piperazine-2-carboxylate is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
To a solution of 7-benzyl-2,4-dichloro-6,8-dihydro-5H-pyrido [3,4-d] pyrimidine (5.00 g, 17.0 mmol) and 1-tert-butyl 2-methylpiperazine-1,2-dicarboxylate (4.24 g, 17.3 mmol) in DMSO (80 mL) was added DIEA (5.49 g, 42.5 mmol, 7.42 mL). After stirring at 55¡ã C. for 12 hours, the mixture was diluted with ethyl acetate (100 mL), washed with brine (3 150 mL), dried over Na 2SO 4, filtered and concentrated under vacuum. The residue was purified by column chromatography (SiO 2, PE/EA=3/1) to give 1-tert-butyl 2-methyl 4-(7-benzyl-2-chloro-6,8-dihydro-5H-pyrido[3,4-d] pyrimidin-4-yl)piperazine-1,2-dicarboxylate (8.00 g, 15.9 mmol, 93.8% yield) as a yellow oil. ES+APCI MS m/z 502.1[M+H] +.
129799-15-1, As the paragraph descriping shows that 129799-15-1 is playing an increasingly important role.
