methyl 4-amino-2-(3-chloropropoxy)benzoate

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a solution of 2,4-dichloro-6-(2,2,2-trifluoroethoxy)-1,3,5-triazine (770 mg, 2.79 mmol) in THF (10 mL) was added methyl 4-amino-2-(3-chloropropoxy)benzoate (681 mg, 2.79 mmol) and Hunig'sBase (1.464 mL, 8.38 mmol). The resulting mixture was stirred for 16 h. The reaction was diluted with DCM and water. The organic layer was collected and dried over sodium sulfate, and concentrated under vacuum. The crude product was purified by silica gel chromatography using 20-40% EtOAc/Hexanes. The product fractions were collected and concentrated under vacuum to give methyl 4-(4-chloro-6-(2,2,2-trifluoroethoxy)-1,3,5-triazin-2-ylamino)-2-(3-chloropropoxy)benzoate as a solid. The organic layer was collected dried over sodium sulfate concentrated under vacuum The crude product was purified by silica gel chromatography The product fractions were collected concentrated under vacuum

反応条件: temp:60.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a solution of methyl 4-amino-2-hydroxybenzoate (500 mg, 2.99 mmol) and 1-bromo-3-chloropropane (0.294 mL, 2.99 mmol) in DMF (3 mL) was added CESIUM CARBONATE (1462 mg, 4.49 mmol). The resulting mixture was stirred at 60° C. for 6 hrs. The reaction mixture was poured into water, extracted with ethyl acetate, washed with brine, dried over MgSO4, concentrated. The crude product was purified by silica gel chromatography using a gradient of 20-50% EtOAc/Hexanes to give 686 mg (94%) methyl 4-amino-2-(3-chloropropoxy)benzoate. extracted with ethyl acetate washed with brine dried over MgSO4 concentrated The crude product was purified by silica gel chromatography
