Synthetic Route of 86770-74-3 ,Some common heterocyclic compound, 86770-74-3, molecular formula is C8H19NO4, 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.
To a solution of 2-(2-(2-(2-aminoethoxy)ethoxy)ethoxy)ethanol (256 mg, 1.32 mmol) in DCM (30 mL) were added BCN-OSu (351 mg, 1.20 mmol) and Et3N (502 muIota_, 364 mg, 3.60 mmol). The resulting solution was stirred for 30 min and washed with a saturated aqueous solution of NH4CI. After separation, the aqueous phase was extracted with DCM (30 mL). The combined organic phases were dried (Na2S04) and concentrated. The residue was purified with column chromatography (MeOH in DCM 0? 10%). The product was obtained as a colourless oil (397 mg, 1.07 mmol, 90%). H NMR (400 MHz, CDCI3) delta (ppm) 5.93 (bs, 1 H), 4.14 (d, J = 8.1 Hz, 2H), 3.77-3.69 (m, 4H), 3.68-3.59 (m, 8H), 3.58-3.52 (m, 2H), 3.42-3.32 (m, 2H), 2.34-2.16 (m, 6H), 1.66-1.51 (m, 2H), 1 .36 (quintet, J = 8.7 Hz, 1 H), 1.00-0.85 (m, 2H).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles. 86770-74-3, 2-(2-(2-(2-Aminoethoxy)ethoxy)ethoxy)ethanol, other downstream synthetic routes, hurry up and to see.
