    Abstract: A process is provided for preparing cis-(+)-hydroxy-5-[2-(dimethylamine)ethyl]-2,3-dihydro-2-(4-methoxyphenyl) -benzothiazepin-4(5H)-one that is a useful intermediate in the preparation of diltiazem. It has been found that the requisite N-alkylation reaction proceeds rapidly and with an excellent yield when the solvent is a mixture of toluene and N-methylpyrrolidin-2-one and the base is finely-divided sodium carbonate under anhydrous conditions. Such diltiazem commonly is used in the treatment of angina pectoris.
