Acetic Acid → HCID 61166465, compound

Participants

Reaction Steps

4-Methoxy-2-nitroaniline (10 g, 59.5 mmol, 1.0 equiv.) and trimethyl-acetaldehyde (9.73 g, 113 mmol, 1.9 equiv.) were dissolved in anhydrous dichloromethane (100 ml). The resulting solution was then treated with acetic acid (18.72 ml, 327 mmol, 5.5 equiv.), followed by sodium triacetoxyborohydride (30.3 g, 143 mmol, 2.4 equiv.). The mixture was stirred at room temperature. When LCMS showed completion of the reaction, the mixture was treated with saturated aqueous NaHCO3, then extracted with EtOAc. The combined organic layers were dried over Na2SO4 and concentrated to give the crude N-(2,2-dimethylpropyl)-4-methoxy-2-nitroaniline (1-3), which was used without purification. LRMS m/z (M+H) 239.0 found, 238.1 required.
