Adding a certain compound to certain chemical reactions, such as: 17247-58-4, name is (Bromomethyl)cyclobutane, belongs to bromides-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 17247-58-4, Product Details of 17247-58-4
A solution of 12.3 g (83 mmol) of cyclobutylcarbinyl bromide (Aldrich) and 13.7 g (91 mmol) of sodium iodide in 150 mL of acetone was heated to reflux overnight and then cooled to room temperature. The inorganic solids were removed by filtration and the acetone and cyclopropylcarbinyl iodide (8.41 g, 46%) were removed by distillation (ambient temperature and 150 torr at 80 C., respectively). A solution of 4.0 g (21.98 mmol) of cyclobutyl carbinyl iodide in 30 mL of anhydrous diethyl ether cooled to -78 C. was cannulated into a solution of 17 mL (21.98 mmol) of 1.3M sec-butyllithium in cyclohexanes and the solution was stirred for 5 minutes. To this mixture was cannulated a solution of 3.0 g (21.98 mmol) of freshly distilled sulfuryl chloride in 110 mL of hexanes cooled to -78 C., the mixture warmed to room temperature over 1 hour and was then carefully concentrated in vacuo. This mixture was redissolved in diethyl ether, washed once with some ice-cold water, dried (MgSO4), filtered, and concentrated carefully. This mixture was redissolved in 30 mL of THF, added dropwise to 500 mL of saturated NH3 in THF and was allowed to stir overnight. The mixture was concentrated in vacuo to a crude yellow solid and was recrystallized from the minimum amount of dichloromethane in hexanes with 1-2 drops of methanol to afford 1.39 g (42%) of cyclobutyl carbinylsulfonamide as a white solid. 1H NMR (CDCl3) delta 1.81-2.03 (m, 4H), 2.14-2.28 (m, 2H), 2.81-2.92 (m, 1H), 3.22 (d, J=7 Hz, 2H), 4.74 (brs, 2H); 13C NMR (CDCl3) delta 19.10, 28.21, 30.64, 60.93; MS m/e 148 (M-1)-. time: 1.73, method B), 818 (M++H)
