YieldReaction ConditionsOperation in experiment
85% With palladium 10% on activated carbon; hydrogen; at 35℃; under 3040.2 Torr; for 4h; Transfer the product B to a 5 L hydrogenation vessel, add 3 g of 10 wtpercent palladium on carbon palladium, heat to 35 ° C, while the introduction of hydrogen pressure to 4atm, continue to heat constant pressure reaction 4 hours, after the end of the reaction, the hydrogen into nitrogen, Adjust the pH to 3-4 with 35 wtpercent concentrated hydrochloric acid, continue heating to 100 ° C, stop the introduction of nitrogen, filter hot, and cool the filtrate to HTC, a large number of precipitated precipitation, precipitate out completely after the filter, the filtrate for organic solvent recovery, filter cake with 400ml deionized water washing, drying, to be 214g isluminolide (4-amino phthalide)
26 g With sodium thiosulfate; In ethanol; for 3h;Reflux; Under stirring at room temperature, in a step upward reaction to the 10g sodium thiosulfate, after stirring at room temperature for 30 minutes. Then heating reflux reaction 3 hours, confirming board 4-nitrosodi phthalic hydrazide has been fully converted to the required products, to stop the reaction, the reaction liquid natural cooling down to room temperature, then filtered, collecting filter cake. Filtrate the spin vaporization recovery 95percent ethanol, the residue combined with the filter cake, is added to the 200 ml water, heating to 80 °C, stirring 30 minutes, there are still some solid insoluble, filter when it is hot. In the filtrate by adding concentrated hydrochloric acid to adjust pH to 9, natural cooling crystallization. Filtering, receive 26g strawcoloured powdered products.
