Procedure

Sodium hydride (95% dry, 80 mg, 3.23 mmol) was added to a stirred solution of EXAMPLE 181A (426 mg, 1.28 mmol) in tetrahydrofuran (10 mL) at room temperature. After stirring for 15 min, the mixture was treated with ethyl iodide (400 mg, 2.56 mmol). The reaction mixture was stirred for 2 h at 55° C. and then quenched with aqueous HCl (1 M, 1 mL) and water was added. The product was extracted with DCM and dried (Sodium sulfate). Evaporation of the solvent gave a residue which was purified by flash chromatography on silica gel eluting with 10% acetone in DCM giving an oil (0.25 g, 54%) which solidified on standing: MS (Ionspray, [M+H]+) m/z 360; Anal. Calcd. (found) for C14H17ClN2O3S2: C, 46.6 (46.5)%; H, 4.7 (4.6)%; N, 7.8 (7.8)%.
