実験手順
2-bromo-1-methyl-4-nitrobenzene (864 mg, 4mmol), oxetan-3-amine hydrochloride (438 mg, 4 mmol), CS2CO3 (3910 mg, 12.00 mmol), palladium(II) acetate (44.9 mg, 0.20 mmol), (R)-(-)-1-[(S)-2-(Dicyclohexylphosphino)ferrocenyl]ethyldi-t- butylphosphine (224 mg, 0.40 mmol) in 1,4-doxane was degased, inflated with Ar and heated at 90 oC for 5h. LCMS showed some product peak. Silica gel 2g was added to the mixture, evaporated all solvents in GeneVac. The sample was dry loaded for purification by ISCO (Hexane/EtOAc=100/10-100/50) N-(2-methyl-5-nitrophenyl)oxetan-3-amine (240 mg, 28.8 %) 1H NMR (400 MHz, CD2Cl2) d: 7.47 (dd, 1H), 7.14 (d, 1H), 6.98 (s, 1H), 4.99 (t, 2H), 4.63 (m, 1H), 4.46 (t, 2H), 4.20(m, 1H), 2.18 (s, 3H). LCMS: 209 [M+H]+.
