To a solution of 270 mg (1.44 mmol) 4-bromo-6-methyl-pyridin-3-ol (Stage 40.4) in DMF (5 mL), 44.8 mg NaH (1.87 mmol) was added and this mixture was stirred for 1 h at rt. 301 mg (1.58 mmol) 2-acetamido-4-(chloromethyl)-1,3-thiazole (Apollo OR15549) was added and stirring was continued at rt for another 17 h. The reaction mixture was poured on water and extracted with EtOAc (2×). The combined organic layers were washed with water and brine, dried (MgSO4) and filtered. The filtrate was concentrated in vacuo to leave 350 mg of the title compound (white solid) considered sufficiently pure without further purification. LCMS: tR=1.36 min, M+H=342 (79Br), 344 (81Br) (method J).
