YieldReaction ConditionsOperation in experiment
52% With pyridine; N-Bromosuccinimide; In tetrahydrofuran; at -78 - 5℃; for 18.25h; To a solution of <strong>[40318-15-8]methyl 4-methyl-1H-pyrrole-3-carboxylate</strong> 35 (5.0 g, 35.9 mmol) in THF (60 mL) was added NBS (6.39 g, 35.9 mmol) at -78 C. After being stirred 15 min at -78 C, pyridine (five drops) was added, and the mixture was stood at 5 C for 18 h in a refrigerator. The mixture was concentrated under reduced pressure, diluted with H2O, and extracted with EtOAc. The extract was washed with brine, dried over Na2SO4, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane/EtOAc = 9/1-2/1) to give 36 (4.05 g, 52%) as a pale yellow solid: 1H NMR (CDCl3) delta 2.23 (3H, s), 3.80 (3H, s), 7.35-7.40 (1H, m), 8.45 (1H, br).
With N-Bromosuccinimide; Reference Example 97 Methyl 5-bromo-4-methyl-1H-pyrrole-3-carboxylate By a similar operation as in Reference Example 40 and using <strong>[40318-15-8]methyl 4-methyl-1H-pyrrole-3-carboxylate</strong> (1.0 g) and N-bromosuccinimide (1.28 g), the title compound was obtained as a pale-yellow solid (yield 489 mg, 31%). 1H-NMR (CDCl3)delta: 2.23 (3H, s), 3.80 (3H, s), 7.37 (1H, d, J=3.0 Hz), 8.40 (1H, brs).
