Related Products of 558-42-9, Adding some certain compound to certain chemical reactions, such as: 558-42-9, name is 1-Chloro-2-methyl-2-propanol,molecular formula is C4H9ClO, 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 558-42-9.
5 g (40.94 mmol) of 4-hydroxybenzaldehyde were initially charged in 50 ml of DMF. 4.45 g (40.94 mmol) of 1-chloro-2-methylpropan-2-ol and 6.08 g (57.32 mmol) of sodium carbonate were added, and the mixture was then stirred at 130° C. overnight. Saturated aqueous sodium bicarbonate solution/ethyl acetate were added to the reaction mixture. The precipitate was filtered off and discarded. The two phases were separated from one another, and the aqueous phase was extracted three times with ethyl acetate. The combined organic phases were dried over magnesium sulfate, filtered and concentrated using a rotary evaporator. The residue was purified by column chromatography on silica gel 60 (mobile phase: cyclohexane/ethyl acetate 5/1?1/2). Yield: 8.6 g (82percent of theory, 76percent pure) LC-MS (Method 4): Rt=1.17 min; MS (ESIpos): m/z=195 [M+H]+. 1H NMR (400 MHz, DMSO-d6): delta=9.87 (s, 1H), 7.86 (d, 2H), 7.12 (d, 2H), 4.70 (s, 1H), 3.84 (s, 2H), 1.21 (s, 6H).
