Methyl iodide → HCID 67153147, compound

Participants

Reaction Steps

step 2—To a solution of 34a (116 mg, 0.276 mmol) in DMF (5 mL) was added sodium hydride (0.022, 0.550 mmol, 60% mineral oil dispersion). After 20 min, methyl iodide (0.040 mL, 0.643 mmol) was added and the resulting suspension was stirred overnight. The reaction mixture was diluted with EtOAc, thrice washed with brine, dried (Na2SO4), filtered and concentrated in vacuo. The crude product was purified by SiO2 chromatography eluting with an EtOAc/hexane gradient (5% to 15% EtOAc) to afford 81 mg (68%) of 5-bromo-1-tert-butyl-2-methoxy-3-[(E)-2-(2-methoxymethyl-4-nitro-phenyl)-vinyl]-benzene (34b) as an orange oil.
