Participants

Reaction Steps

A mixture of 4-fluorophenylhydrazine hydrochloride (1.83 g, 11.25 mM) and 1-indanone (1.49 g) in ethanol (20 cm3) was heated to reflux, and conc. hydrochloric acid was (1 cm3) added. Heating was continued for 5 hours, and the reaction mixture was cooled. The product which crystallised out from the cold solution as coloured platelets, was collected by filtration and dried (1.90 g, 75%). M.p. 225°-227° C. (from ethyl acetate/petrol [60°-80 ]). 1H NMR (CDCl3) δ: 8.3 (1H, br, s), 7.6-6.9 (7H, m), 3.70 (2H, s).
