Downstream synthetic route of 2941-58-4

The synthetic route of 2941-58-4 has been constantly updated, and we look forward to future research findings.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.2941-58-4,2-Bromo-6-methoxybenzothiazole,as a common compound, the synthetic route is as follows.

To a stined solution of 2-bromo-6-methoxybenzo[d]thiazole (8.00 g, 32.8 mmol) in dichloromethane (20 mL) at 15 C was added tribromoborane (9.1 mL, 98 mmol) dropwise. The resulting mixture was heated at 40 C for 6 h then poured into ice water. The precipitate was filtered and the filtrate was extracted with dichloromethane (40 mL x 3). The precipitate and the organic layers were combined, dried over Na2504,and concentratedto give the title compound.MS: m/z = 229.9, 231.9 (M + 1). ?H NMR (400 MHz, CD3OD): oe7.74 (d, J= 8.8 Hz, 1H), 7.28 (d,J=2.4Hz, 1H),7.00(dd,J,=8.8Hz, J2=2.4Hz, 1H)., 2941-58-4

The synthetic route of 2941-58-4 has been constantly updated, and we look forward to future research findings.
