Application of 50868-73-0,Some common heterocyclic compound, 50868-73-0, name is 2-Methoxy-6-methylaniline, molecular formula is C8H11NO, 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.
Step A: 2-cyclopentyl-N-(2-methoxy-6-methylphenyl)acetamide 3-cyclopentylpropionyl chloride (2.24 g, 15.31 mmol) was added to a mixture of 2-methoxy-6-methylaniline (2.0 g, 14.58 mmol) and triethylamine (2.24 mL, 16.04 mmol) in DCM at 0 C. The reaction mixture was progressively warmed to room temperature and stirred overnight. Ethyl acetate (200 ml) was added to the reaction mixture which was washed twice with HCl aq., 1N (100 ml). The organic layer was dried over MgSO4 and concentrated. The oily crude product was subjected to crystallization form hexanes to yield to the title compound (3.55 g, 14.37 mmol, 99%) as white crystal.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 2-Methoxy-6-methylaniline, its application will become more common.
