“…Acid hydrolysis then yielded the target molecules 1 or 2 . Molecules 3 a – 5 a were prepared by benzoyl chloride catalysed coupling32 of 6 with 4‐methylpyridine, 4‐methylquinoline or 9‐methylacridine,33 respectively. Subsequent base hydrolysis then gave 3 – 5…”

“…Methyl 2‐{2‐(2‐{2‐[di(2‐methoxy‐2‐oxoethyl)amino]‐5‐methylphenoxy}ethoxy)(2‐methoxy‐2‐oxoethyl)‐4‐[( E )‐2‐(4‐pyridyl)‐1‐ethenyl]anilino}acetate (3 a) : Compound 3 a was prepared using a procedure adapted from Kost et al32 Benzoyl chloride (0.10 mL) was added dropwise to stirred, ice‐cold 4‐methylpyridine (1.3 mL) under a nitrogen stream, whereupon a precipitate of (4‐methyl‐1‐pyridiniumyl)(phenyl)methanone chloride was produced. This was then allowed to warm to ambient temperature and 6 (0.80 g) was added.…”
