Synthetic Route of 185836-35-5,Some common heterocyclic compound, 185836-35-5, name is 4-(Benzyloxy)-2-fluorobenzonitrile, molecular formula is C14H10FNO, 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.
16.1. 6-(Phenylmethoxy)-1,2-benzisothiazol-3-amine A mixture of 13.2 g (0.058 mol) of 2-fluoro-4-(phenylmethoxy)benzonitrile and 1.85 g (0.058 mol) of sulphur in 15 ml (0.58 mol) of ammonia and 50 ml of methylglycol is brought to 100 C. in an autoclave over 5 hours. The methylglycol is subsequently evaporated off under reduced pressure. The mixture is taken up in dichloromethane, the insoluble material is filtered off, and then the solvent is evaporated off under reduced pressure. The product is purified by chromatography on a silica column with cyclohexane and ethyl acetate in proportions of 60:40. Subsequently, a second purification by chromatography on a silica column with a mixture of diisopropyl ether and methanol in proportions of 99:1 leads to 1.7 g of product. Melting point: 158 C.
The synthetic route of 185836-35-5 has been constantly updated, and we look forward to future research findings.
