Triethylamine → n-[3-(Dimethylamino)propyl]-1-methyl-4-nitro-1h-pyrrole-2-carboxamide

참여 물질

반응 단계

A solution of 1-methyl-4-nitro-1H-pyrrole-2-carbonyl chloride (0.254 g, 1.35 mmol; see Preparation 1(ii) above) in DCM (10 mL), is added dropwise to a solution of DMPA (0.153 g, 5.05 mmol) (Aldrich), NEt3 (0.152 g, 1.5 mmol), in DCM (10 mL) over 15 min. The resulting solution was allowed to stir overnight, before quenching the reaction with a 5% NaOH solution (20 mL). The DCM fraction was then dried over MgSO4, filtered and the solvent removed under reduced pressure to yield the sub-title compound (0.254 g, 74%).
