Reaction Conditions

Reaction Steps

To a solution of 4-(3-(dimethylamino)prop-1-ynyl)-2-methyl-5-nitrophenyl methyl carbonate (120 mg; 0.41 mmol) in ethanol (2.7 mL) and glacial acetic acid (1.5 mL) was added Fe (92 mg, 1.64 mmol). The mixture was heated at 60° C. for 1 h and then cooled to room temperature. The mixture was diluted with water and carefully neutralized with solid Na2CO3. The resulting solution was extracted with ethyl acetate. The combined organic extracts were dried over MgSO4 and concentrated in vacuo. The residue was purified by silica gel chromatography (0-20% ethyl acetate/hexanes) to provide 5-amino-4-(3-(dimethylamino)prop-1-ynyl)-2-methylphenyl methyl carbonate (85 mg, 79% yield). LC/MS m/z 218.3 [M+H]+.
