Reaction Steps

1,1-Dioxo-3-butyl-3-ethyl-5-phenyl-7-bromo-8-carboxymethoxy-2,3,4,5-tetrahydro-1,5-benzothiazepine (Method 9; 50 mg, 0.098 mmol) and Cs2CO3 (51 mg, 0.15 mmol) were added to DMF (2.0 ml) and ethyl thioglycolate (0.02 ml, 0.15 mmol) was added. The reaction mixture was subjected to microwave irradiation in a Smith Synthesiser at 150° C. for 5 min. The reaction mixture was diluted with water (100 ml), made acidic with HCl (1 M), extracted with DCM (3×10 ml) and the collected organic layers were dried (MgSO4) to give the crude title compound (54 mg). M/z 550.2.
