Reaction Steps

The mixture of 4-(4-chloro-6-methylquinolin-2-yl)-2,3,4,5-tetrahydro-1,4-benzothiazepine 1,1-dioxide (150 mg, 0.40 mmol, prepared in analogy to the one in Example 2-1) and L-alanine (360 mg, 4.0 mmol) in phenol (360 mg) was heated at 150° C. overnight. After being cooled to room temperature, the mixture was purified by preparative HPLC to afford the pure product as a solid. MS obsd.
