Some tips on 696-59-3

As the paragraph descriping shows that 696-59-3 is playing an increasingly important role.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.696-59-3,2,5-Dimethoxytetrahydrofuran,as a common compound, the synthetic route is as follows.

696-59-3, 3-Chloroaniline (10.6 ml) and 2,5-dimethoxytetrahydrofuran (12.9 ml) are heated at 110C in acetic acid (100 ml) for 5 hours and 30 minutes. To the cooled reaction mixture, water (500 ml) is added and the reaction is stirred overnight. The brown precipitate formed is filtered and subsequently dissolved in dichloromethane, washed with aqueous sodium hydrogencarbonate (saturated) (100 ml), dried over sodium sulphate and concentrated in vacuo. l-(3-Chloro-phenyl)-lH-pyrrole is isolated as black solid (35.2 g). IH-NMR (400 MHz, CDCl3): 6.38 (t, 2H), 7.10 (t, 2H), 7.30 (m, 4H).
