Reference of 22911-21-3, A common heterocyclic compound, 22911-21-3, name is 1-Chloro-4-(trimethoxymethyl)benzene, molecular formula is C10H13ClO3, its 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.
1-Chloroisoquinolin-5-amine A mixture of 1-chloro-5-nitroisoquinoline (450 mg, 0.0022 mol), stannous chloride dihydrate (2.4 g, 0.011 mol), and EtOAc (50 mL) was stirred under reflux under an atmosphere of nitrogen for 3 h. After cooling, the mixture was poured into ice-water and basified to pH 10.0 with aq. Na2CO3. The organic phase was separated and the aqueous phase was extracted with EtOAc. The combined organic layers were washed with brine, dried (Na2SO4) and concentrated under vacuum. The residue was purified by column chromatography on silica gel to give the product as a light yellow solid. LC-MS: 3.17 min, 179.2 & 181.2 (M+1).
The synthetic route of 22911-21-3 has been constantly updated, and we look forward to future research findings.
