To a mixture of methyl 4-chloro-2-(2,3-dihydro-1,4-benzothiazepin-4(5H)-yl)quinoline-6-carboxylate (400 mg, 1.04 mmol, prepared in analogy to 4-(4-chloro-6-methylquinolin-2-yl)-8-methoxy-2,3,4,5-tetrahydro-1,4-benzothiazepine in Example 1-1) in tetrahydrofuran (5 mL) and a saturated solution of ammonia in methanol (30 mL) was heated with stirring for 16 hours at 120° C. in a sealed tube. The reaction mixture was concentrated in vacuo to afford 300 mg of the product (yield was 78%).
