4-Nitroaniline → HCID 13450497, compound

Participants

Reaction Steps

To a mixture of p-nitroaniline (0.50 g, 0.0036 mol) and 4-dimethylaminopyridine (DMAP, 0.531 g, 0.00434 mol) in tetrahydrofuran (10 mL, 0.1 mol) was added 3-chloropropyl chloridocarbonate (0.480 mL, 0.00398 mol). The mixture was stirred at room temperature for 1 h, then treated with 1.0 M of potassium tert-butoxide in tetrahydrofuran (7.96 mL, 0.00796 mol) at room temperature for 2 h, then quenched with aqueous ammonium chloride, extracted with EtOAc. The combined organic layers were washed with water, brine, dried and evaporated to dryness. The residue was purified on silica gel, eluting with 0 to 10% MeOH in dichloromethane, to provide the product (260 mg, 32.32%). LCMS (M+H) 222.9.
