Related Products of 178312-48-6 ,Some common heterocyclic compound, 178312-48-6, molecular formula is C7H12F2O, 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.
The above (4, 4-difluorocyclohexyl) methanol was dissolved in 5 ml of pyridine. Thereto 2.2 g of p- toluenesulfonyl chloride was added at 0C and the mixture was stirred at room temperature overnight. Thereafter, the reaction mixture was concentrated under reduced pressure. The residue was dissolved in ethyl acetate, washed successively with water, dilute hydrochloric acid and aqueous saturated sodium chloride, dried over anhydrous magnesium sulfate, and then concentrated under reduced pressure. The residue was subjected to silica gel column chromatography to obtain 3.1 g of 4, 4- difluorocyclohexylmethyl p-toluenesulfonate. 4, 4-Difluorocyclohexylmethyl p-toluenesulfonate: lH-NMR (CDC13, TMS) 5 (ppm): 1.18-1. 37 (2H, m), 1.56-1. 86 (5H, m), 2.00-2. 17 (2H, br), 2.46 (3H, s), 3. 86 (2H, d), 7. 35 (2H, d), 7.78 (2H, d).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles. 178312-48-6, (4,4-Difluorocyclohexyl)methanol, other downstream synthetic routes, hurry up and to see.
