Methanamine, N-methoxy-, hydrochloride (1:1) → HCID 58368653, compound

Participants

Reaction Steps

To a mixture of 8-(3-fluorophenyl)-5-vinylquinoline-7-carboxylic acid (66 mg, 0.22 mmol), N,O-dimethylhydroxylamine hydrochloride (32.9 mg, 0.338 mmol) in N,N-dimethylformamide (0.4 mL) was added benzotriazol-1-yloxytris(dimethylamino) phosphonium hexafluorophosphate (0.149 g, 0.338 mmol). After stirring at room temperature for 30 minutes, N,N-diisopropylethylamine (0.118 mL, 0.675 mmol) was added to the resulting mixture. The reaction was stirred at room temperature overnight, quenched with water and extracted with ethyl acetate. The combined organic layers were washed with brine, dried over sodium sulfate and concentrated to dryness under reduced pressure. The resdiue was purified on silica gel, eluting 0 to 50% ethyl acetate in hexane, to give the desired product (32 mg, 42%). LCMS calculated for C20H18FN2O2 (M+H)+: m/z=337.1; Found: 337.1.
