With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.236406-22-7,1-Boc-4-(Aminomethyl)-4-methylpiperidine,as a common compound, the synthetic route is as follows.
HATU (294 mg, 0.8 mmol) was added to the mixture of 6-methyl-7-oxo-6,7-dihydro- 1 H- pyrrolo[2,3-c]pyridine-4-carboxylic acid (Intermediate C) (135 mg, 0.7 mmol), tert-butyl 4- (aminomefhyl)-4-methylpiperidine-l-carboxylate (160 mg, 0.7 mmol), and diisopropylethylamine (181 mg, 1.4 mmol) in DMF (3 mL). After addition, the reaction mixture was stirred at room temperature for 2 h, at which time LCMS indicated that the reaction had gone to completion. The mixture was quenched by addition of water (5 mL) and extracted with ethyl acetate (2 x 10 mL). The combined organic extracts were washed with brine, dried over sodium sulfate and concentrated under reduced pressure to give the crude title compound (275 mg, 94% yield) as light brown oil. This crude material was used directly in the next step. LCMS M/Z (M+H) 402.9.
236406-22-7, As the paragraph descriping shows that 236406-22-7 is playing an increasingly important role.
