실험 절차

Heat a solution of 3.1 gm of the product of Example 8 and 40 ml phosphorous oxychloride at 100° for 20 minutes. Cool to room temperature and remove the phosphorous oxychloride under reduced pressure. Partition the residue between chloroform and an aqueous solution of sodium bicarbonate. Separate the chloroform layer, wash it with brine and dry over potassium carbonate. Filter the dry solution and remove the chloroform under reduced pressure. Dissolve the residue in absolute ethanol and add an ethanolic solution of hydrogen chloride. Remove the ethanol under reduced pressure. Triturate the resulting residue in ether to obtain 3-methyl-8-(2-phenylethyl)imidazo[1,5-a]pyridine hydrochloride hemihydrate as an amorphous, hygroscopic solid.
