Procedure

4-[2-(2-Imino-4,4-dimethyl-1,3-oxazolidin-3-yl)-1,3-thiazol-4-yl]benzonitrile (0.075 g, 0.25 mmol), prepared in Example 4, was dissolved in tetrahydrofuran (2 mL) followed by triethylamine (0.069 mL, 0.5 mmol) and acetylchloride (0.039 g, 0.5 mmol). The mixture was stirred 4 h, poured into water, extracted with ethyl acetate, and dried over anhydrous MgSO4. The solvent was evaporated and residue triturated with hexane/ethyl acetate (95/5), collected and dried to give the title compound (0.055 g, 64%). HRMS: calcd for C17H16N4O2S+H+, 341.10667; found (ESI, [M+H]+), 341.1075; HPLC purity 96.5% at 210-370 nm, 9.4 min.; 96.0% at 250 nm, 9.4 min.; the Xterra® RP18 column, 3.5μ, 150×4.6 mm column, 1.2 mL/min, 85/15-5/95 (Ammon. Form. Buff. Ph=3.5/ACN+MeOH) for 10 min, hold 4 min.
