Diisopropylethylamine → 3-chloro-N-(2-morpholin-4-ylethyl)-4-nitro-benzamide

Participants

Reaction Steps

3-chloro-4-nitro-benzoyl chloride (Intermediate 54; 1.1 g, 5.00 mmol) was dissolved in DCM (10 mL) and N,N-diisopropylethylamine (1.05 mL, 6.00 mmol) added. The mixture was cooled in an ice/water bath and 4-(2-aminoethyl)morpholine (Aldrich; 0.66 mL, 5.00 mmol) in DCM (5 mL) added dropwise. The mixture was allowed to warm to room temperature and stirred for 0.5 hr. The reaction mixture was washed with brine, 2N NaOH, dried (MgSO4) and concentrated. Column chromatography of the residue (2% MeoH/DCM) gave the title compound as a yellow solid. (1.2 g, 76%)
