Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 87-13-8, name is Diethyl 2-(ethoxymethylene)malonate, This compound has unique chemical properties. The synthetic route is as follows., SDS of cas: 87-13-8
2-Phenylaminomethylene-malonic acid diethyl ester A mixture of aniline (25.6 g, 0.28 mol) and diethyl 2-(ethoxymethylene)malonate (62.4 g, 0.29 mol) was heated at 140-150 C. for 2 h. The mixture was cooled to room temperature and dried under reduced pressure to afford 2-phenylaminomethylene-malonic acid diethyl ester as a solid, which was used in the next step without further purification. 1H NMR (d-DMSO) delta 11.00 (d, 1H), 8.54 (d, J=13.6 Hz, 1H), 7.36-7.39 (m, 2H), 7.13-7.17 (m, 3H), 4.17-4.33 (m, 4H), 1.18-1.40 (m, 6H).
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 87-13-8.
