2516-33-8, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 2516-33-8, name is Cyclopropylmethanol, molecular formula is C4H8O, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
Sodium hydride (4.83 g, 0.12 mol) was added into cyclopropanemethanol (CAN 2516-33- 8, 30 g) at 0C and the mixture was stirred at 0C for 1 h. Then to the mixture was added methyl 5-bromo-6-chloro-pyridine-2-carboxylic acid methyl ester (3 g, 12.75 mmol).The obtained solution was heated to 90C for 2 h. Then the mixture was evaporated to dryness, the residue was dissolved in 40 mL of water, and adjusted to pH = 4 with hydrochloric acid (3 N), and extracted with ethyl acetate (3 x 30 mL). The combined organic layer was washed with water (2 x 30 mL) and brine (2 x 50 mL) then evaporated to dryness to obtain the product as a white solid (2.5 g, 76.7%); MS (EI): m/e = 272.0 [M+H]+.
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. 2516-33-8, Cyclopropylmethanol, other downstream synthetic routes, hurry up and to see.
