Procedure
3 g of (±)-cis-2-(4-methoxyphenyl)-3-hydroxy-8-chloro-2,3-dihydro-1,5-benzothiazepin-4(5H)-one and 1.7 g of 2-(N-methyl-N-ethylamino)ethyl chloride hydrochloride are treated in the same manner as described in Example 5. The product is converted to its hydrochloride and recrystallized from a mixture of ethanol and ether. 3.1 g of (±)-cis-2-(4-methoxyphenyl)-3-hydroxy-5-[2-(N-methyl-N-ethylamino)ethyl]-8-chloro-2,3-dihydro-1,5-benzothiazepin-4(5H)-one hydrochloride are thereby obtained as colorless needles.
