A mixture of 3.4 g (0.028 mol) of freshly distilled allyl bromide, 7 g (0.025 mol) of α-(p-chlorophenyl)-α-phenylimidazole-2-methanol (prepared according to Example IV), 1.2 g (0.030 mol) of sodium hydroxide, 0.050 g of picric acid and 50 ml. of acetonitrile was refluxed for 5 hours. The warm reaction mixture was filtered and water was added to the filtrate. The precipitate formed was filtered off, washed with water and petroleum ether (boiling range 40°-60° C.) and three times crystallised from isopropyl alcohol. 1-Allyl-α-(p-chlorophenyl)-α-phenylimidazole-2-methanol was obtained. Melting point 165°-165.5° C.
