YieldReaction ConditionsOperation in experiment
93% With triethyl phosphite; for 16h;Heating / reflux; Synthesis example 11 2-methoxycarbazole 8.36 g (36.7 mmol) 4'-methoxy-2-nitro-1,1'-biphenyl in 40 ml triethylphosphite is refluxed during 16 hours in argon atmosphere. The mixture was allowed to cool to room temperature, upon which the product precipitates. Filtration and washing with methanol gave 6.67 g (93 %) of a white solid 1H NMR (DMSO-d6): delta11.10 (s, 1H), 8.00 (dd, J=1.5 Hz, J=8 Hz, 1H), 7.8 (d, J=8 Hz, 1H), 7.44 (dd, J=1.5 Hz, J=8 Hz, 1H), 7.30 (dt, J=1.5 Hz, J=8 Hz, 1H), 7.12 (dt, J=1.5 Hz, J=8 Hz, 1H), 6.98 (d, J=1.5 Hz, 1H), 6.78 (dd, J=1.5 Hz, J=8 Hz, 1H), 3.83 (s, 3H). 13C NMR (DMSO-d6): delta 158, 141, 140, 124, 123, 121, 119, 118, 116, 111, 108, 94, 55. mp: 239 C.
70% In a 500 mL round-bottom flask was added 4?-methoxy-2-nitro-1,1?-biphenyl (10.3 g, 44.7 mmol) and triethyl phosphite (44.2 mL, 258 mmol). The reaction mixture was heated to reflux at 165 C. in an oil bath under nitrogen for 18 hours. The reaction mixture was cooled to room temperature and 60 mL of 6 N HCl was added dropwise over a period of 30 min. with continuous stirring (exothermic reaction). After the addition, the reaction was heated for 3 hours at 80 C., resulting in the formation of copious precipitate. After cooling to room temperature, water was added (100 mL) and the reaction mixture was neutralized with 50% NaOH (aq.) (60-70 mL, exothermic reaction). The resulting mixture was extracted with 3×250 mL EtOAc and the combined organic layers were washed with brine, dried over Na2SO4, filtered and solvent removed under reduced pressure. To this was added 5-10 mL DCM and the insoluble solid was filtered and washed with hexane to give 6.2 g (70%) of 2-methoxy-9H-carbazole as a light yellow solid. The product was confirmed by GC/MS and NMR.
