80.7% | With hydrogenchloride; platinum(IV) oxide; hydrogen In methanol at 10 - 40℃; for 18 h; | (20.0 g), methanol (180 mL) and 0.1 m hydrochloric acid are added to a hydrogenation reaction, and the reaction is carried out in the same manner as in the literature (Org. Process Res. Dev.2011, 15, 831-840). Specifically, 3- (4-nitrophenyl) Kettle, then add PtO2(2 g) was evacuated and the nitrogen was exchanged and the reaction mixture was cooled to 10 ° C2The reaction mixture was heated to 40 ° C, stirred for 18 h, cooled to room temperature, neutralized with sodium hydroxide solution, extracted with isopropyl acetate, concentrated, and added to the reaction mixture. The amount of N- (4- (pyridin-3-yl) phenyl) hydroxylamine was 4.2percent |

Example 1 Compound 3 (36.0 g, 0.19 mol) was dissolved in 190 mL of methylene chloride under a nitrogen atmosphere,Diisopropylethylamine (27.0 g, 0.21 mol) was added and the temperature was lowered to -60 ° C. Trifluoromethanesulfonic anhydride (59.2 g,0.21 mol) was added and reacted at this temperature. After the reaction, water was added, the temperature was raised to room temperature, the mixture was extracted with ethyl acetate, and saturated sodium bicarbonateAfter washing and drying of the organic phase, the solvent was distilled off under reduced pressure to give 44.5 g of compound 3 as a light yellow solid. Example 2 A mixture of compound 3 (39.0 g, 0.12 p-nitrophenyl boronate mol) under nitrogen was added 130 mL of tetrahydrofuranAfter dissolution, (31.4 g, 0.13 mol), palladium tetrakistriphenylphosphine (6.9 g, 6.0 mmol), potassium carbonate(33.1 g, 0.13 mol) and heated to reflux temperature and reacted at this temperature for 8 hours, after which time the system was lowered to roomThe reaction solution was filtered through celite and the filtrate was evaporated under reduced pressure to a partial solvent, the crystals precipitated at low temperature, filtered to give a mixture of compounds 5,6The compound was 37.5 g as a light brown solid. Example 3 In an autoclave, 110 mL of methanol was added to a mixture of compounds 5 and 6 (19.0 g, 0.065 mol), 30 mL of acetic acid was added, 1.5 g of palladium hydroxide was added,After the introduction of hydrogen, after 12 at atmospheric pressure for 24 hours, after the reaction,The solid was filtered off and most of the methanol in the filtrate was evaporated under reduced pressure. 130 mL of 1 mL sodium hydroxide solution was added and the mixture was stirred for 20 minutes.The mixture was extracted twice with ethyl acetate (2 * 100 mL), the organic phase was washed once with saturated citric acid (100 mL) and the organic phase was washed with anhydrous sodium sulfateDrying, the organic phase pressure steaming to give a pale yellow solid 9.3g. |
