Reaction Conditions:
with Dess-Martin periodane in dichloromethane at 0 - 20; for 2 h;
Steps:
1 Step 1: 2-Bromothiazole-5 -carbaldehyde
Into a 500-mL round-bottom flask, was placed (2-bromothiazol-5-yl)methanol (20 g, 103 mmol), DCM (200 mL). This was followed by the addition of Dess-Martin reagent (46 g, 103 mmol) in portions at 0°C. The resulting solution was stirred for 2 h at RT and then was concentrated under vacuum. The residue was applied onto a silica gel column and eluted with ethyl acetate/petroleum ether (1:20 to 1:10). This resulted in 18 g (91%) of the title compound as awhite solid. MS-ESI: 193.9, 191.9 (M+1).
