“…N ‐(1‐Hexylheptyl)‐ N ′‐(4‐ N ′′‐methylcarbaldimin‐ N ′′‐oxidobenzyl)perylene‐3,4:9,10‐tetracarboxylic bisimide (3) : Comopund 2 12 (1.10 g, 1.59 mmol), N ‐methylhydroxylamine hydrochloride (200 mg, 2.39 mmol), and NaHCO 3 (287 mg, 3.31 mmol) were dissolved in CH 2 Cl 2 (50 mL). The resulting solution was treated with MgSO 4 (400 mg), heated under reflux for 5 h, stirred at room temperature for 16 h, filtered and evaporated, and the residue was purified by column separation (silica gel, dichloromethane/methanol 30:1).…”
