Reaction Conditions

Reaction Steps

A mixture of 5-methyl-2,3,4,5-tetrahydro-1,4-benzothiazepine (1.0 g, 5.58 mmol) and 2,4-dichloro-6-methylquinoline (1.7 g, 8.02 mmol) was heated with stirring in a 2 mL of microwave process vial for 5 hours at 170° C. under microwave irradiation. The solvent was removed by concentration in vacuo. The residue was purified by flash column chromatography to give 560 mg of the mixture of 5-methyl-2,3,4,5-tetrahydro-1,4-benzothiazepine and 4-(4-chloro-6-methylquinolin-2-yl)-5-methyl-2,3,4,5-tetrahydro-1,4-benzothiazepine.
