Reference of 4316-51-2, A common heterocyclic compound, 4316-51-2, name is 4-Methoxytriphenylamine, molecular formula is C19H17NO, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
(1) Synthesis of 4,4′-Diformyl-4″-methoxytriphenylamine (8c) Reactions were conducted in the same manner as in (4) in Example 2 except that 20.0 g (0.075 mol) of 4-methoxytriphenylamine (7c) was used in place of triphenylamine (7a). Thus, 19.0 g of 4,4′-diformyl-4″-methoxytriphenylamine (8c) was obtained. Theoretical yield, 76.5%; m.p., 113-114 C. Spectral data for this compound are as follows. 1 H-NMR spectrum (400 MHz, CDCl3, deltappm): 3.85 (3H, s), 6.94 (2H, d, J=9.0 Hz), 7.12 (2H, d, J=9.0 Hz), 7.17 (4H, d, J=8.7 Hz), 7.56 (4H, d, J=8.7 Hz), 9.88 (2H, s)
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
