Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 69113-59-3, name is 3-Iodobenzonitrile, A new synthetic method of this compound is introduced below., Formula: C7H4IN
EXAMPLE 18.1 (+-)-3-{(6R,9aS)-[(3-chlorophenyl)ethynyl]octahydro-2H-pyrido[1,2-a]pyrazin-2-yl}pyrazine-2-carbonitrile Bis(triphenylphosphine)palladium(II) dichloride (0.018 mmol) and copper(I) iodide (0.03 mmol) were added to a microwave vial with a stir bar. 3-iodobenzonitrile (0.45 mmol) and (+-)-3-[(6R,9aS)-6-ethynyloctahydro-2H-pyrido[1,2-a]pyrazin-2-yl]pyrazine-2-carbonitrile (0.3 mmol, 80.2 mg) was dissolved in THF (1 mL) and added to the microwave vial with stirring, followed by Et3N (1 mL). The vial was sealed and microwaved at 90 C for 6 min. The resulting mixture was then diluted with DCM and washed with water. The organic phase was purified by column chromatography to yield the desired product (80.3 mg, 73%). 1H NMR 300 MHz, (CDCl3) delta (ppm): 1.41 (m, 2H); 1.72 (m, 1H); 1.87 (m, 2H); 2.12 (m, 1H); 2.21 (m, 1H); 2.31 (td, 1H); 2.95 (dd, 1H); 3.09 (dd, 1H); 3.33 (td, 1H); 3.69 (d, 1H); 4.35 (d, 1H); 4.51 (d, 1H); 7.43 (t, 1H); 7.58 (d, 1H); 7.64 (d, 1H); 7.69 (s, 1H); 8.00 (d, 1H); 8.25 (d, 1H).
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.
