A THF solution of LiHMDS (1 M in THF, 2500 muL, 2.500 mmol) was added dropwise. After 5 min, the cooling bath was removed. After a total of 22 min, HCl (5 N, 0.5 mL) was added. After 5 min, EtOAc (10 mL) and saturated NH4Cl (10 mL) were added. The organic layer was washed with water (2 x 5 mL). The combined aqueous layers were extracted with EtOAc (2 x 5 mL). The combined organic layers were dried over Na2SO4 and concentrated. The resulting residue was suspended in MeOH (5 mL) and filtered. The solid was washed with MeOH (2 x 2 mL), DCM (3 x 3 mL) and EtOAc (3 x 3 mL) to give the first batch of product as a brown solid. The combined washings were concentrated and purified on silica using 0-3% MeOH in DCM. The dark blue fraction contained the desired product (m/z 346) as a second batch. The combined product batches was suspended in ether (4 mL) and filtered to give the final product as a green solid (60 mg).

49% | With trifluoroacetic acid; at 20℃; for 2h; | [00677] Intermediate 73: 5-fluoro-6-methoxy-pyridin-3-amine[00678] tert-Butyl N-(5-fluoro-6-methoxy-3-pyridyl)carbamate (315mg, 1 .3Ommol) was stirred in trifluoroacetic acid (1 .99mL, 26.01 mmol) for 2 hours. The reaction mixture was reduced in vacuo and the residue taken up in water (100 mL) and 1 M HCI (100 mL) and extracted with EtOAc (5OmL). To the aqueous layer was added solid sodium carbonate until a neutral/slightly basic pH was obtained. The aqueous was then further extracted with EtOAc (3 x 5OmL), organic fractionscollected, passed through phase separating filter paper and solvent reduced in vacuo to give 5-fluoro-6-methoxy-pyridin-3-amine (91mg, 0.64mmol, 49% yield) as a dark red oil.1H NMR (CDCI3,400MHZ) O/ppm: 7.45 (1H, d, J= 2.5Hz), 6.85 (1H, dd, J= 11.3Hz, 2.5Hz), 3.97(3H, 5).MS Method 2: RT: 0.91 mm, 143.0 m/z [M+H] |
19 mg | 2nd Step TFA (2 ml) was added to tert-butyl (5-fluoro-6-methoxypyridin-3-yl)carbamate (279 mg) obtained in the 1st step, followed by stirring at room temperature for 1 hour. The solvent was distilled away under reduced pressure and a 5M sodium hydroxide aqueous solution was added to the obtained residue at 0 C. so as to alkalify the mixture, followed by extraction with ethyl acetate. The organic layers were washed with saturated saline and dried over anhydrous sodium sulfate and the solvent was distilled away under reduced pressure. A light brown solid of 5-fluoro-6-methoxypyridin-3-amine (19 mg) was thus obtained. MS (ESI m/z): 143 (M+H) |
