in the presence of polyphosphoric acid for 10–20 min in a boiling water bath ? (65%)
in the presence of 70% perchloric acid at reflux for 30 min (70%)
in the presence of Amberlite IR-120 (cation exchange resin sulfonic acid type) ? at 160° for 2–3 h (76%)
Preparation by reaction of propionitrile with resorcinol (Hoesch reaction) (75%) (65%) (46%)(35%)
Preparation by reaction of propionic anhydride with resorcinol
in the presence of Amberlite IR-120 (cation exchange resin sulfonic acid ? type) at 160° for 2–3 h (82%)
in the presence of concentrated sulfuric acid (small drops) at 130° for some ? min (60%)
