4-氟苯基异氰酸酯

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Example 26 was synthesized by the following way: to a stirred solution of 2-aminopyrazine (683 mg, 7.18 mmol) in 50 mL of MeOH were added 4-fluorobenzaldehyde (1.16 mL, 10.8 mmol), 1-fluoro-4-isocyanobenzene (1.0 g, 8.25 mmol), and followed by 1.0 N HClO4 in MeOH (0.72 mL, 0.72 mmol). The reaction mixture was stirred at room temperature overnight. The reaction mixture was concentrated and the residue was subjected to flash chromatography purification. The collected organic solution was concentrated to give the title compound as yellow oil. Example 26 was synthesized by the following way The reaction mixture was concentrated the residue was subjected to flash chromatography purification The collected organic solution was concentrated
