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.100058-61-5, name is 3-(Benzyloxy)cyclobutanol, molecular formula is C11H14O2, molecular weight is 178.23, as common compound, the synthetic route is as follows.category: alcohols-buliding-blocks

Step 2. 3-(benzyloxy)cyclobutyl methanesulfonate [0641] A 100-mL round-bottom flask was charged with 3-(benzyloxy)cyclobutanol (1.83 g, 10.3 mmol), dichloromethane (20 mL) and triethylamine (2.15 mL, 15.4 mmol), and the solution was cooled to 0 C. Methanesulfonyl chloride (1.20 mL, 1.77 g, 15.4 mmol) was added dropwise, and the resulting solution stirred for 30 min at 0 C. The reaction mixture was poured into water (30 mL) and extracted with dichloromethane (2 x 30 mL). The combined organic layers were dried over anhydrous sodium sulfate, filtered, and concentrated to afford 3-(benzyloxy)cyclobutyl methanesulfonate (2.60 g, 99%) as a light yellow solid. MS (ESI, pos. ion) m/z 257[M+H]+.

At the same time, in my other blogs, there are other synthetic methods of this type of compound,100058-61-5, 3-(Benzyloxy)cyclobutanol, and friends who are interested can also refer to it.

Electric Literature of 100058-61-5, In the chemical reaction process,reaction time,type of solvent,can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product.An updated downstream synthesis route of 100058-61-5 as follows.

Step 1: 4-((1r,3r)-3-(benzyloxy)cyclobutoxy)pyridine To a solution of pyridin-4-ol (3.20 g, 33.66 mmol, 1.5 eq) and 3-benzyloxycyclobutanol (4 g, 22.44 mmol, 1 eq) in tetrahydrofuran (200 mL) was added triphenylphosphine (7.06 g, 26.93 mmol, 1.2 eq) and diisopropyl azodicarboxylate (5.45 g, 26.93 mmol, 1.2 eq) in one portion at 10 C. under nitrogen. The mixture was stirred at 50 C. for 12 hours. The reaction mixture was concentrated under reduced pressure to remove tetrahydrofuran. Water (50 mL) was poured into the mixture and stirred for 1 minute. The aqueous phase was extracted with dichloromethane (50 mL*3). The combined organic phase was washed with brine (50 mL*2), dried with anhydrous sodium sulfate, filtered and concentrated in vacuum. The residue was purified by silica gel column chromatography (petroleum ether: tetrahydrofuran from 20:1 to 5:1). HPLC showed 41% of the product in 254 mm. The residue was purified by flash C18 column chromatography [acetonitrile: water (0.5% ammonium hydroxide)=5%-50%]. Compound 4-(3-benzyloxycyclobutoxy) pyridine (3.2 g, 12.53 mmol, 55% yield) was obtained as a white solid.

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,100058-61-5, its application will become more common.
