求助图片中化合物合成文献？WO2009/4593, 2009, A2 To a cooled solution of 3,4-dihydroxyphenyl acetyl chloride (750 g) in N,N-dimethyl acetamide (2.1 L), N-methyl benzyl amine (912 g) was added drop wise at about 10-15 0C. After the addition, temperature of the reaction mixture was raised to 30-35 0C and stirred for another 2-4 hours. After completion of the reaction, the reaction mixture was filtered and washed with isopropyl alcohol (1.0 L). The filtrate was cooled to about 20 0C and the pH was adjusted to about 5.5 with dilute HCl (150 mL). Water (8 L) was added and further stirred for 15 minutes. pH of the reaction mixture was adjusted to 8.5 with dilute ammonia (240 mL). Solid so obtained was filtered and wet solid was washed with water (4 L). The wet solid was suspended in water (10 L) and pH was adjusted to 5.5. The suspension was stirred for 1 hour and the solid obtained was filtered and dried. Yield: 1027 g查看更多
文献中所说的sealed tube是什么？就叫微波反应管，你做微波反应，为啥要 放超声波清洗器里面可以反应？ 微波反应管 我们清洗也不用超声，它那个玻璃特殊，超声的化可能会有损伤，你做高温微波反应时候 由于内部压力较大，可能会爆裂。 换气的话 ... 没用过 文献说degassed by bubbling with argon and sealed.after 3 days of sonication.sonication不就是超声吗 查看更多
