Related Products of 6326-79-0,Some common heterocyclic compound, 6326-79-0, name is 6-Bromoisatin, molecular formula is C8H4BrNO2, 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 of 6-bromoindoline-2,3-dione (0.504 g,2.23 mmol)in acetonitrile (11 mL)was added K2C03 (1.23 g,8.92 mmol)then iodomethane (0.278 mL,4.46 mmol). The reactionmixture was heated at 60 oc for 1.5 h. After cooling to room temperature,water (30 mL)wasadded and the mixture was extracted with DCM (30 mL x 3). The combined organic layers were washed with brine (30 mL),dried over anhydrous Na2S04 and then concentrated in underreduced pressure to give the title compound (0.506 g,95%)that required no further purification.1HNMR(400MHz,CDCl3)87.46(dd,J=7.9,l.OHz,1H),7.32-7.28(m,1H),7.08(d,J=1.5 Hz,1H),3.25 (d,J = 0.6 Hz,3H).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 6-Bromoisatin, its application will become more common.
