Participants

Reaction Steps

To a suspension of 1,2-dimethylpyrrole-3-carboxylic acid (2.085 g; 15 mmol) in 1,2-dichloroethane (40 mL) there is added 1-chloro-N,N,2-trimethyl-prop-1-en-1-amine (2.37 mL; 17.9 mmol), and the solution formed is stirred for 1 hour. To the resulting solution there is added, dropwise, an ice-cold solution of 4-benzyloxy-N-methyl-aniline (3.73 g; 15 mmol) and N-ethyl-N-isopropyl-propan-2-amine (7.75 mL; 45 mmol) in 1,2-dichloroethane (40 mL). The reaction mixture is stirred at ambient temperature for 1 hour; it is then diluted with dichloromethane (250 mL) and washed with water (2×30 mL), dried over Na2SO4 and evaporated. The crude product is triturated with diethyl ether and the solid formed is filtered off to yield the title compound.
