Analyzing the synthesis route of 2-Cyclopropylethanol

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. 2566-44-1, 2-Cyclopropylethanol, other downstream synthetic routes, hurry up and to see.

Synthetic Route of 2566-44-1 ,Some common heterocyclic compound, 2566-44-1, molecular formula is C5H10O, 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.

To 2-cyclopropylethanol at 0 C. (0.98 g, 11 mmol) and pyridine (2.4 mL, 30 mmol) in DCM (15 mL) was added 4-methylbenzene-1-sulfonyl chloride (22 g, 11 mmol). The cold bath was removed and the mixture allowed to warm to room temperature for 14 h. The reaction mixture was diluted with water and Et2O and the phases were separated. The organic phase was washed sequentially with water, 10% aqueous HCl and brine, dried (MgSO4) filtered and concentrated under reduced pressure to give Compound 4a (2.0 g, 74%) as a clear colorless oil. Compound 4a was used in the next step without further purification. MS m/z=241.4 (M+H). 1H NMR (400 MHz, chloroform-d) delta 7.77 (d, J=8.1 Hz, 2H), 7.32 (d, J=8.4 Hz, 2H), 4.06 (t, J=6.7 Hz, 2H), 2.42 (s, 3H), 1.56-1.45 (m, 2H), 0.70-0.57 (m, 1H), 0.44-0.32 (m, 2H), 0.04-0.10 (m, 2H).
