With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.938465-52-2,1-Chloro-5H-pyrido[4,3-b]indole-4-carboxamide,as a common compound, the synthetic route is as follows.
To a solution of 4-(4-fluorophenyl)- 1 -oxa-4, 8-diazaspiro[5. Sjundecan-5-one (120 mg, 0.45 mmol) in NMP (3 mL) was added 1-chloro-5H-pyrido[4,3-bjindole-4-carboxamide (123 mg, 0.Smmol) and DIEA (174 mg, 1.35 mmol), and the mixture was heated under microwave irradiation for 1.5 h at 150 C.The mixture was purified with prep-HPLC to give 1-(4-(4-fluorophenyl)-5 -oxo- 1 -oxa-4, 8-diazaspiro[5.5j undecan-8-yl)-5H-pyrido [4,3-bj indole-4- carboxamide. ?H NMR (400 MHz, CD3OD) 3 8.51 (s, 1H), 8.03 (d, J=8.0 Hz, 1H), 7.82 (d, J=8.0 Hz, 1H), 7.62 (t, J=7.7 Hz, 1H), 7.54 – 7.44 (m, 1H), 7.31 – 7.23 (m, 2H), 7.14 – 7.06 (m, 2H), 4.40 (d, J=13.3 Hz, 1H), 4.27 – 4.14 (m, 2H), 4.00 – 3.90 (m, 1H), 3.80 – 3.66 (m, 3H), 3.64- 3.52 (m, 1H), 2.54 – 2.39 (m, 1H), 2.38 – 2.22 (m, 2H), 1.94 – 1.79 (m, 1H) ppm., 938465-52-2
As the paragraph descriping shows that 938465-52-2 is playing an increasingly important role.
