Reaction Steps
To a solution of ethyl 2-bromothiazole-4-carboxylate (2.0 g, 8.40 mmol) in DMF (15 mL) was added K2CO3 (1.16 g, 8.40 mmol) followed by benzyl mercaptan (1.07 g, 8.40 mmol) in DMF (5 mL) over 20 min. Upon completion of addition, the reaction mixture was stirred at RT for 16 h. After this time, the reaction mixture was diluted with water and extracted in EtOAc. The combined organic layers were dried over Na2SO4, filtered and concentrated under reduced pressure. The resulting concentrate was purified by silica gel chromatography (10% EtOAc in hexane) to provide ethyl 2-(benzylthio)thiazole-4-carboxylate (2.0 g, 87% yield). 1H NMR (400 MHz, DMSO-d6) δ (ppm): 8.42 (s, 1H); 7.47-45 (m, 2H); 7.36-7.28 (m, 3H); 4.52 (s, 2H); 4.31 (q, 2H, J=7.2 Hz); 1.31 (t, 3H, J=7.2 Hz).
