Procedure

A mixture of 4-chloro-2-(1,1-dioxido-2,3-dihydro-1,4-benzothiazepin-4 (5H)-yl)quinoline-6-carboxamide (300 mg, 0.75 mmol) and propane-1,3-diamine (306 mg, 4.14 mmol) was heated with stirring in a sealed 10 mL of microwave process vial for 1 hour at 120° C. under microwave irradiation. The reaction mixture was purified by preparative HPLC to afford 23.5 mg of the desired product (yield was 7.2%). MS obsd. (ESI+) [(M+H)+] 440, 1H NMR (400 MHz, CD3OD) δ ppm 8.70-8.69 (d, J=1.6 Hz, 1 H), 8.18-8.15 (m, 1 H), 8.10-8.08 (dd, J=1.2, 7.6 Hz, 1 H), 7.88-7.84 (t, J=6.8 Hz, 2 H), 7.73-7.72 (m, 1 H), 7.60-7.59 (m, 1 H), 6.01 (s, 1 H), 5.34 (s, 2 H), 4.55 (s, 2 H), 3.75 (s, 2 H), 3.64-3.60 (t, J=6.8 Hz, 1 H), 3.11-3.09 (m, 2 H), 2.18-2.09 (m, 2 H).
