実験手順
A solution of 2-[(phenyl)methylene]-3-oxobutanoic acid, methyl ester (13.0 g., 63.7 mmole) in dry dimethylformamide (20 ml.) is treated dropwise with 2-aminothiophenol (8.85 g. of 90%, 63.7 mmole). A slight release of heat is noted. The reaction is stirred at room temperature for 6 hours and then heated at 65° for 72 hours. It is cooled to room temperature and diluted with ether. The resulting solution is thoroughly washed with water, sodium bicarbonate and brine. After drying over anydrous magnesium sulfate, the solvent is stripped off to give a yellow solid. It is triturated with isopropyl ether and filtered off to provide 6.93 g. of light yellow crystals. Recrystallization from isopropyl ether-dichloromethane gives an analytically pure sample of 2,5-dihydro-4-methyl-2-phenyl-1,5-benzothiazepine-3-carboxylic acid, methyl ester; m.p. 154°-156°. TLC(silica gel, hexane:acetone, 70:30) Rf =0.35.
