실험 절차

Ethyl 5-(bromomethyl)-2-chloro-1,3-thiazole-4-carboxylate (Intermediate 180, 920 mg; 3.2 mmol) was dissolved in acetonitrile dried over molecular sieves. The solution was cooled to 0 C and NMO (570 mg; 1.5 equiv.) was added in a single portion. The reaction was monitored by LC/MS. An additional 1.5 equivalents of NMO was added in two portions over two hours. The reaction was concentrated to a solid residue, redissolved in EtOAc and washed with H2O. Dried the organic over Na2SO4, filtered and concentrated. No further purification. MS (ES) MH+: 220, 222 for C7H6ClNO3S.
