Reference of 578008-32-9<\/a>,Some common heterocyclic compound, 578008-32-9, name is tert-Butyl 3-amino-5-methyl-1H-pyrazole-1-carboxylate, molecular formula is C9H15N3O2, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.<\/p>\n

Step C: To 4-chloro-2-(difluoro(5-fluoropyridin-2-yl)methyl)-7-methoxyquinazoline (355 mg, 0.91 mmol) in DMF (5.0 mL) at rt were added tert-butyl 3-amino-5-methyl-1H-pyrazole-1-carboxylate (0.448 g, 2.27 mmol) and DIEA (0.40 mL, 2.3 mmol), and the mixture was stirred at rt for 3 h. The mixture was purified by preparative reverse-phase HPLC using TFA as a modifier, and the fractions containing the desired product were neutralized with saturated aq NaHCO3 and extracted with EtOAc (100 mL). The organic layer was separated, washed with brine (2\u00d710 mL), dried over MgSO4, filtered, and concentrated under reduced pressure to afford tert-butyl 3-(2-(difluoro(5-fluoropyridin-2-yl)methyl)-7-methoxyquinazolin-4-ylamino)-5-methyl-1H-pyrazole-1-carboxylate as a clear oil (104 mg).<\/p>\n

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route tert-Butyl 3-amino-5-methyl-1H-pyrazole-1-carboxylate, its application will become more common.<\/p>\n
