In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 111-95-5 as follows. 111-95-5
Bis(2-methoxyethyl)amine (9.0 mL, 60.8 mmol, 1.8 eq.) was added dropwise to a solutionof PCl3 (3.0 mL, 34.3 mmol) in dry hexane (90 mL) under N2 at 0 C. The resulting white slurrywas stirred at 20 C for 1 h, filtered and washed with hexanes (3x 100 mL). The solvent wasremoved (rotavap) and the residue distilled under reduced pressure (125 C, 100 mmHg). Theproduct was isolated as a colorless clear liquid (5.14 g, 64%).Data for 29a:1H-NMR: (500 MHz, CDCl3)delta 3.33 (s, 6 H, OCH3), 3.49 (s, 8 H, 1-H, 2-H).13C-NMR: (125 MHz, CDCl3)delta 48.6 (d, J = 16.8 Hz), 58.9, 71.1 (d, J = 2.6 Hz).31P NMR: (200 MHz, CDCl3)delta -84.2.
According to the analysis of related databases, 111-95-5, the application of this compound in the production field has become more and more popular.
