Application of 74115-13-2, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 74115-13-2, name is 5-Bromo-3-pyridinol, molecular formula is C5H4BrNO, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
Preparation of intermediate 3-(benzyloxy)-5-bromopyridine (LV) is depicted below in Scheme 11. Step 1 (0839) To a solution of 5-bromopyridin-3-ol (L) (174 mg, 1.0 mmol) in DMF (3 mL) was added potassium carbonate (415 mg, 3.0 mmol). The slurry was heated at 90 C. for 1 hour and then cooled to 25 C. The (bromomethyl)benzene (LIV) (171 mg, 1.0 mmol) was added and the mixture was stirred at 25 C. overnight. The reaction was worked-up using a saturated sodium bicarbonate and ethyl acetate extraction. The product was purified by ISCO column eluted with 40-100% EtOAc-Hexanes. The 3-(benzyloxy)-5-bromopyridine (LV) (105 mg, 0.398 mmol, 39.8% yield) was obtained as yellow oil. MS: 266.1. ESIMS found for C12H10BrNO m/z 266.1 (M+H).
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 74115-13-2, 5-Bromo-3-pyridinol.
