Reaction Steps

A mixture of 4-(4-chloroquinolin-2-yl)-2,3,4,5-tetrahydro-1,4-benzothiazepin-8-ol 1,1-dioxide (374.0 mg, 1.0 mmol), 3-bromo-propan-1-ol (0.37 mL, 3.0 mmol) and potassium carbonate (415.0 mg, 3.0 mmol) in N,N-dimethylformamide (1.5 mL) was heated with stirring at 70° C. for 2 hours. After being cooled to room temperature, the resulting mixture was extracted with ethyl acetate (150 mL×2). The combined organic layers were washed with water (50 mL×2) and a saturated aqueous ammonium chloride solution (50 mL×2), dried over anhydrous sodium sulfate and then concentrated in vacuo to afford 421.6 mg of the crude product as a yellow oil which was used for next step without further purification. MS obsd. (ESI+) [(M+H)+] 433.
