Application of 155310-11-5, With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.155310-11-5, name is 3-Amino-2,2-difluoropropan-1-ol, molecular formula is C3H7F2NO, molecular weight is 111.0906, as common compound, the synthetic route is as follows.
50 mL of THF was added to 50 mL of aqueous solution of the compound 41, and then reacted with 1.13 g (1.0 eq., 5.17 mmol) of Boc2O at 0 C. It was then stirred overnight. After confirming by TLC the disappearance of the reacting materials, THF was removed by using an evaporator. The residual liquid was added with ethyl acetate, and liquid fractionation extraction was performed 3 times. The collected organic layer was washed with a saturated aqueous solution of NaCl. After drying over magnesium sulfate, it was concentrated under reduced pressure by using an evaporator in water bath at 40 C. As a result, the solids are obtained, which were then washed with hexane to obtain 1.08 g of the desired compound 42 (2 step yield of 99% from the compound 18). 1H-NMR signal assignment is given in the following. 1H-NMR (500 MHz, CDCl3) delta1.46 (9H, s), 3.54 (2H, ddd), 3.67 (2H, ddd), 3.95 (1H, m), 4.98 (1H, br).
The chemical industry reduces the impact on the environment during synthesis 155310-11-5, I believe this compound will play a more active role in future production and life.
