실험 절차

Magnesium (0.29 g, 12 g atom) in THF (60 mL) was treated with (2-bromoethyl)-benzene (1.64 mL) and reacted for 18 hours. The suspension was treated with solid 7-Methyl-imidazo [2,1-b]benzothiazole-3-carboxaldehyde (Formula K-3) (0.65 g) and reacted for 2 hours. The reaction mixture was decanted into cold 5% ammonium chloride solution and precipitated 7-Methyl-α-(2-phenylethyl)imidazo[2,1-b]benzothiazole-3-methanol (Formula K-4) (0.96 g) was filtered. An aliquot was crystallized from methylene chloride/ethanol solution to yield pure 7-Methyl-α-(2-phenylethyl) imidazo[2,1-b]benzothiazole-3-methanol (Formula K-4), m.p. 209-210°.
