Versuchsvorschrift

A mixture of methylsalicylate (4.36 g, 28.69 mmol) and cyclopropylamine (1.64 g, 28.69 mmol) was heated at 80–100° C. for 3 h. An additional 0.5 equivalent of cyclopropylamine was added and the reaction mixture was kept at 70° C. for overnight. The reaction mixture was co-evaporated with toluene and the residue was purified by silica gel flash chromatography to give the subtitle compound (2.71 g).
