4-Fluorobenzaldehyde → HCID 49856295, compound

Participants

Reaction Steps

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.
