Analyzing the synthesis route of 1768-64-5

1768-64-5, As the paragraph descriping shows that 1768-64-5 is playing an increasingly important role.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.1768-64-5,4-Chlorotetrahydropyran,as a common compound, the synthetic route is as follows.

70 mg (1.76 mmol, 1.1 eq.) of NaH was added into the solution of 455 mg (1.4 mmol, 1 eq.) 2 in DMF, and stirred for 1 hr at rt. 211 mg (1.76 mmol, 1.1 eq.) of 4-chloro-2H-tetrahydropyran was then added and stirred overnight. After the reaction was complete, water was added, and then all the solvent was removed by filtration and the product was purified by column chromatography to obtain 942 mg of 3, with a yield of 60%.
