In a flame dried round-bottomed flask equipped with a magnetic stir bar and under inert atmosphere (N2), a solution of (2-bromothiazol-5-yl)methanol (WO 2009/077990, p. 92) (1.19 g, 6.11 mmol) in CH2Cl2 (4.0 mL) was treated with MeI (0.46 mL, 7.33 mmol) followed by Ag2O (2.12 g, 9.16 mmol) and the resulting mixture (protected form light) was stirred overnight at 40° C. The reaction mixture was filtered and the solvent was removed under reduced pressure. Purification of the residue by FC (7:3 hept-EA) gave the title compound as a colorless oil: TLC: rf (7:3 hept-EA)=0.33. LC-MS-conditions 07: tR=0.66 min, [M+H]+=209.93.
