Some common heterocyclic compound, 645-36-3, name is 2,2-Diethoxyethanamine, molecular formula is C6H15NO2, 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. Product Details of 645-36-3
2,2-Diethoxyethylamine (470 muL, 3.23 mmol) was added to a suspension of pyrimidine 9 (0.63 g, 2.67 mmol) in i-PrOH (30 mL), and the mixture was stirred at r.t. until the starting compound has dissolved. Et3N (560 muL, 4.0 mmol) was then added and the mixture was stirred for a further 45 min. H2O (50 mL) was added and the product was extracted with CH2Cl2 (2 × 50 mL). The organic layers were combined, washed with H2O (2 × 20 mL), dried (Na2SO4), and concentrated. The residue was purified by flash chromatography(silica gel, CH2Cl2; Rf = 0.42) to give a yellow solid; yield: 0.61 g(69%); mp 65.5-67.5 C.IR (KBr): 3380 (NH) cm-1. 1H NMR (300 MHz, CDCl3): delta = 1.27 (t, J = 6.9 Hz, 6 H, 2 × CH3),2.55 (s, 3 H, SCH3), 3.60 (dq, 2J = 9.3 Hz, 3J = 6.9 Hz, 2 H,2 × CHAHBCH3), 3.72-3.83 (m, 4 H, NCH2 and 2 × CHAHBCH3),4.09 (s, 3 H, OCH3), 4.68 (t, J = 5.4 Hz, 1 H, OCH), 8.84 (br s, 1 H,NH).13C NMR (75 MHz, CDCl3): delta = 14.8, 15.6, 44.3, 55.7, 63.2, 100.5,113.5, 156.6, 163.8, 174.6.Anal. Calcd for C12H20N4O5S: C, 43.36; H, 6.07. Found: C, 43.68;H, 6.11.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 645-36-3, its application will become more common.
