Reaction Steps

A mixture of N-[(3-aminooxetan-3-yl)methyl]-2-(7-methoxy-1,1-dioxido-2,3-dihydro-1,4-benzothiazepin-4(5H)-yl)-6-methylquinolin-4-amine (20 mg, 0.044 mmol, prepared in analogy to Example 1-5), potassium hydroxide (24 mg, 0.44 mmol) in dimethylsulfoxide (2 mL) was heated with stirring in a sealed 5 mL of microwave process via for 20 minutes at 100° C. under microwave irradiation. The resulting mixture was purified by preparative HPLC to afford 6 mg of the product (yield was 30%). MS obsd.
