Related Products of 1663-61-2,Some common heterocyclic compound, 1663-61-2, name is (Triethoxymethyl)benzene, molecular formula is C13H20O3, 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.
The product of Example 33D (62 mg, 0.2 mmol) was treated with triethyl orthobenzoate (Aldrich, 0.5 mL) in DMF (1 mL) at 100° C. for 10 h. It was then concentrated. The title product was purified by preparative HPLC (Xterra.(TM)., column, Xterra RP-18, 5 mum, 30.x.100 mm. Eluting Solvent, MeCN/H2O (NH4HCO3, 0.1 M, pH=10), (v. 90/10 to 10/90 over 20 min.) Flow rate, 75 mL/min., uv, 250 nm) as solid (40.0 mg, 50percent). 1H NMR (500 MHz, CD3OD) delta 1.52-1.64 (m, 1 H), 1.68-1.80 (m, 1 H), 1.80-1.92 (m, 1 H), 2.06-2.18 (m, 1 H), 2.25-2.31 (m, 1 H), 2.75-3.10 (m, 5 H), 3.39-3.49 (m, 1 H), 5.14-5.27 (m, 1 H), 7.55-7.66 (m, 3 H), 7.69 (dd, J=8.5, 1.8 Hz, 1 H), 7.81 (d, J=8.2 Hz, 1 H), 8.00 (d, J=1.5 Hz, 1 H), 8.27 (dd, J=8.1, 1.7 Hz, 2 H), 8.89 (s, 2 H) ppm; MS (DCl/NH3): 399 (M+H)+.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route (Triethoxymethyl)benzene, its application will become more common.
