Related Products of 928-51-8 ,Some common heterocyclic compound, 928-51-8, molecular formula is C4H9ClO, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.
To a solution of2b(6.52 g, 50.90 mmol) in pyridine (20 mL) was successively added toluene-4-sulfonylchloride (TsCl, 9.72 g, 50.90 mmol) under nitrogen atmosphere, the mixture was stirred at 0 C for 2 h. The resulting mixture was poured into water (110 mL), extracted with ethyl acetate (EA, 2 × 70 mL), The combined organic layers were washed with hydrochloric acid (2 M, 50 mL) and brine, dried over anhydrous Na2SO4and concentrated under vacuum to give3b(10.54 g, 79%) as a colorless oil, Rf(PE /EA, 5:1) = 0.21.1H NMR (CDCl3, 400 MHz) delta = 7.79 (d, J=8.2 Hz, 2H), 7.36 (d, J=8.2 Hz, 2H), 4.07 (t, J=5.6 Hz, 2H), 3.50 (t, J=5.7 Hz, 2H), 2.46 (s, 3H), 1.86-1.79(m, 2H).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,928-51-8, its application will become more common.
