With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.55512-82-8,3-Bromoisothiazole,as a common compound, the synthetic route is as follows.
Intermediate 123d was reacted with 3-bromoisothiazole in a method analogous to Example 122 to give Example 123 (5.9 mg, 11.5 muiotaetaomicron, 46percent). LC-MS (Method Al) RT = 1.39 min, MS (ESI) m/z: 512.4 (M+H)+. H NMR (500 MHz, DMSO-cfe) delta 9.18 (d, 7=4.6 Hz, 1H), 8.12 (br d, 7=7.9 Hz, 1H), 8.09 – 8.01 (m, 2H), 7.75 (br d, 7=7.9 Hz, 1H), 7.17 (br d, 7=7.9 Hz, 2H), 7.07 (br d, 7=7.9 Hz, 2H), 4.68 (s, 2H), 2.32 (t, 7=7.6 Hz, 2H), 1.90 – 1.77 (m, 6H), 1.67 (br d, 7=6.7 Hz, 2H), 1.49 (quin, 7=7.5 Hz, 2H), 1.27 (dq, 7=14.9, 7.4 Hz, 2H), 0.81 (t, 7=7.3 Hz, 3H) (1 exchangeable proton not observed).
The synthetic route of 55512-82-8 has been constantly updated, and we look forward to future research findings.
