74% | With hydrogen bromide; copper(I) bromide; sodium nitrite; In water; at 0 - 60℃; for 2h; | REAGENT PREPARATION 20: 2-bromo-3-(methyloxy)benzoic acid:[00932] To 2-amino-3-(methyloxy)benzoic acid (4.00 g, 23.9 mmol) in 10% aqueous hydrobromic acid (54 ml) at O0C was added sodium nitrite (1.65 g, 23.9 mmol) in water (17 ml). To this solution was added dropwise a solution of copper (I) <n="391"/>bromide (3.78 g, 26.3 mmol) in 48% hydrobromic acid (22 ml) and heated to 6O0C for 2 h. The mixture was cooled to O0C, and the resultant precipitate was collected by filtration, washed with cold water and recrystallized from water to give pure 2-bromo- 3-(methyloxy)benzoic acid (4.07g, 74%). MS (EI) for C8H7BrO3: 232 (MH+). |

80% | With sulfuric acid; for 20h;Heating / reflux; | STEP l : To a solution of <strong>[88377-29-1]2-bromo-3-methoxybenzoic acid</strong> (718 mg, 3.11 mmol) in methanol (20 mL) was added a catalytic amount of concentrated sulfuric acid and the mixture was brought to reflux for 20 h. On cooling to room temperature, the solution was concentrated and the residue was taken into ethyl acetate and washed with water, saturated aqueous sodium bicarbonate (2x) and brine then dried over sodium sulfate. The solution was then filtered and concentrated to give methyl 2- bromo-3-methoxybenzoate (610 mg, 80percent). MS (EI) for C9H9BrO3: 245 (MH+). |

84% | General procedure: To a solution of 2-bromo-6-methoxybenzoic acid (104 mg, 397 mumol) in CH2Cl2 (3.0 mL) were added chloromethlenedimethyliminium chloride (50.8 mg, 397 mumol) at 0 °C under Ar atmosphere, then the mixture was stirred at room temperature for 1 h. At 0 °C, 2-(4-butylaminophenyl)-1,1,1,3,3,3-hexafluoropropan-2-ol (29g)24 (50.0 mg, 159 mumol) and Et3N (166 mul, 1.19 mmol) then the mixture was stirred for 3 h, and was allowed to warm to room temperature. At 0 °C, the mixture was diluted with ethyl acetate and then water was added. The organic layer was separated and washed with brine, and dried over Na2SO4, and concentrated under reduced pressure. The residue was purified by column chromatography (n-hexane/AcOEt = 1:0-1:1) to give 30g (73.5 mg, 139 mumol, 88percent) as a colorless oil. | |
84% | General procedure: Prepared from 10c and <strong>[88377-29-1]2-bromo-3-methoxybenzoic acid</strong> in accordance with general procedure C. White solid (84percent); 1H NMR (500 MHz, CDCl3) delta 7.51 (d, 2H, J = 8.5 Hz), 7.22 (m, 2H), 7.00 (dd, 1H, J = 7.9, 7.9 Hz), 6.66 (d, 1H, J = 7.9 Hz), 6.59 (d, 1H, J = 7.9 Hz), 4.05-3.90 (m, 2H), 3.80 (s, 3H), 1.73-1.63 (m, 2H), 1.50-1.35 (m, 2H), 0.94 (t, 3H, J = 7.3 Hz); MS (FAB) m/z 528 (M+H)+. |

100% | With 4-methyl-morpholine; 4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium chloride; In acetonitrile; at 20℃; for 17h; | (1a) 2-Bromo-N,3-dimethoxy-N-methylbenzamide <strong>[88377-29-1]2-Bromo-3 methoxy benzoic acid</strong> (14.2 g, 61.5 mmol) was dissolved in acetonitrile (250 mL), added with 4-methylmorpholine (13.5 mL, 123 mmol), N-methoxy methanamine hydrochloride (7.19 g, 73.8 mmol), and 4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholin-4-ium chloride (20.4 g, 73.8 mmol), and stirred for 17 hours at room temperature. 1 N aqueous hydrochloric acid solution was added to the reaction solution, which was then extracted with ethyl acetate. The organic layers were combined, washed with saturated brine, and dried over anhydrous sodium sulfate. The solvent was distilled off under reduced pressure. The residue was purified by silica gel column chromatography (hexane : ethyl acetate, 85 : 15 to 25 : 75, V/V) to give the title compound as a colorless oily substance (16.8 g, quantitative). |
