With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.14774-36-8,(Tetrahydropyran-3-yl)methanol,as a common compound, the synthetic route is as follows.

To a solution of (tetrahydropyran-3-yl)-methanol (Matrix, 1.67 g, 14.4 mmol) in 15 mL of CH2Cl2 and 15 mL of pyridine was added p- toluenesulfonyl chloride (2.9 g, 15.1 mmol) in portions over 10 minutes. The mixture stirred at ambient temperature for 18 hours and was quenched with 10 mL of saturated, aqueous NaHCCh. The layers were separated and the aqueous phase was extracted three 5 mL of portions OfCH2Cl2. The combined organic extracts were dried over anhydrous Na2SO4, filtered and concentrated under reduced pressure. Purification via column chromatography (SiO2, 70% hexanes in ethyl acetate) afforded the title compound. MS (DCI/NH3) m/z 288 (M+NH4)+, 14774-36-8

Intermediate 13: 3-(Bromomethyl)tetrahvdro-2H-pyranTo tetrahydro-2H-pyran-3-ylmethanol (1g) in dry dichloromethane (28 ml) at 0C and under nitrogen, was added triethylamine (2.7 ml) in one go, followed by methanesulphonyl chloride (0.87 ml) dropwise over 1 minute. The reaction was allowed to warm to room temperature and left at this temperature overnight. The reaction mixture was diluted with dichloromethane (20 ml) and washed with saturated aqueous sodium bicarbonate (20 ml). The organic layer was passed through a hydrophobic frit to dry and concentrated in vacuo to yield a yellow oil., 14774-36-8

Analyzing the synthesis route of 14774-36-8

As the paragraph descriping shows that 14774-36-8 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.14774-36-8,(Tetrahydropyran-3-yl)methanol,as a common compound, the synthetic route is as follows.

[00175] At rt, to a suspension of 4,5-dichloro-3,6-dioxocyclohexa-1 ,4-diene-1 ,2- dicarbonitrile (1 .216 g, 5.356 mmol), TBAB (1 .727 mg, 5.356 mmol) and PPh3 (1 .405 g, 5.356 mmol) in DCM (15 mL) was added a solution of 15.1 (360 mg, 3.151 mmol) in DCM (10 mL) dropwise quickly. After addition, the reaction mixture turned to a brown solution and was stirred at rt for another 1 h. Then it was purified by column chromatography on silica gel (pH=8~9, eluent: PE/EA=10:1) directly to give crude title compound (140 mg, 25%) as a colorless oil., 14774-36-8
