With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.934-98-5,2-(4-Methylpiperazin-1-yl)ethanamine,as a common compound, the synthetic route is as follows.
934-98-5, Example 42G ethyl (7R,20S)-18-chloro-10-{[2-(2-methoxyphenyl)pyrimidin-4-yl]methoxy}-19-methyl-15-[2-(4-methylpiperazin-1-yl)ethyl]-1-(prop-1-yn-1-yl)-7,8,15,16-tetrahydro-14H-17,20-etheno-13,9-(metheno)-6-oxa-2-thia-3,5,15-triazacyclooctadeca[1,2,3-cd]indene-7-carboxylate To a mixture of Example 42F (100 mg) in 13 mL dichloromethane at 0¡ã C. were added 50 mg 4 A molecular sieves and sodium triacetoxyborohydride (84 mg) followed by 2-(4-methylpiperazin-1-yl)ethanamine (19.68 muL). The mixture was stirred at room temperature for 3 hours, and was partitioned between saturated aqueous sodium bicarbonate mixture and dichloromethane. The aqueous phase was extracted with dichloromethane. The combined organic phases were dried over magnesium sulfate and filtered. The filtrate was concentrated, and the residue was purified by silica gel chromatography, eluting with 5-12percent methanol in dichloromethane, to provide the title compound. MS (ESI) m/z 872.3 (M+H)+.
934-98-5 2-(4-Methylpiperazin-1-yl)ethanamine 70284, apiperazines compound, is more and more widely used in various fields.
