With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.73579-08-5,1-Methyl-4-(methylamino)piperidine,as a common compound, the synthetic route is as follows.
To a mixture of Scheme 43 compound 1 (1.0 g, 4.90 mmol), Scheme 43 compound 2 (630 mg, 4.90 mmol), Cs2C03 (4.8 g, 14.80 mmol) and Xantphos (286 mg, 0.49 mmol) in dry toluene (10 mL) was added Pd(OAc)2 (111 mg, 0.49 mmol) and the reaction mixture was heated to 100 ¡ãC for 4 h. After TLC showed the starting material was completely consumed, the reaction mixture was cooled to RT, passed through a pad of celite and washed with EtOAc. The filtrate was washed with water and brine, dried over Na2S04 and concentrated to give a residue which was purified by flash chromatography on silica gel (eluting with CH2Cl2/MeOH 100/0 gradually increasing to 95/5) to give Scheme 43 compound 3 (1.0 g, 83percent) as a yellow solid. MS [ESI, MH+] = 251.15., 73579-08-5
The synthetic route of 73579-08-5 has been constantly updated, and we look forward to future research findings.
