Imidazole → Methyl 1-(1-(tert-butyldimethylsilyloxy)-2-methylpropan-2-yl)-6-oxo-1,6-dihydropyridine-3-carboxylate

Participants

Reaction Steps

A solution of methyl 1-(1-hydroxy-2-methylpropan-2-yl)-6-oxo-1,6-dihydropyridine-3-carboxylate (2000 mg, 8.88 mmol), 1H-imidazole (1.51 mg, 22.2 mmol), and chloro-tert-butyldimethylsilane (1405 mg, 9.32 mmol) in DMF (10 mL) was stirred overnight at 23° C. The mixture was partitioned between CH2Cl2 and 5% NaHCO3. The organic was dried over MgSO4 and reduced to an oil under reduced pressure from toluene. MS (ESI pos. ion) m/z (MH+): 340. Calc'd exact mass for C17H29NO4Si: 339.
