Procedure

A mixture of 3-{[2-(1,1-dioxido-2,3-dihydro-1,4-benzothiazepin-4(5H)-yl)-6-methylquinolin-4-yl]amino}propanenitrile (100 mg, 0.25 mmol), sodium azide (48 mg, 0.98 mmol), dimethyl formamide (2 ml) and ammonium chloride (52.6 mg, 0.98 mmol) was heated at 80° C. in an oil bath overnight. The resulting mixture was diluted with water and extracted with dichloromethane (10 mL×3). The combined organic layers were washed with brine, dried over sodium sulfate and concentrated in vacuo. The residue was purified by flash column chromatography (eluting with 10% methanol in dichloromethane) to afford 20 mg of the desired product as a white solid. MS obsd.
