실험 절차

A mixture of N-[2-(3,4-dimethoxyphenyl)ethyl]-4-methyl-2-tritylamino-5-thiazolecarboxamide (5.0 g) and polyphospholic acid (116% as H3PO4, 50 g) was stirred at 100° C. for 10 hours. After the reaction mixture was cooled, water (250 ml) was added and stirred for 1 hour. After removal of insoluble materials by filtration, and filtrate was neutralized with sodium carbonate. From the aqueous solution was extracted the desired compound with chloroform, and the extract was dried over magnesium sulfate. The solvent was evaporated under reduced pressure, and the residue was triturated in diisopropyl ether to afford 1-(2-amino-4-methylthiazol-5-yl)-6,7-dimethoxy-3,4-dihydroisoquinoline (0.67 g).
