Reaction Steps

A mixture of 1-[4-chloro-2-(1,1-dioxido-2,3-dihydro-1,4-benzothiazepin-4(5H)-yl)quinolin-6-yl]ethanol (150 mg, 0.387 mmol) and propane-1,3-diamine (55 mg, 0.74 mmol) was heated with stirring in a sealed 0.5 mL of microwave process vial for 1.5 hours at 150° C. under microwave irradiation. The reaction mixture was purified by preparative HPLC and SPE to afford 70.2 mg of the desired product (yield was 41.2%). MS obsd.
