Participants

Reaction Steps

2-Phenylthiopyrrole (1.75 g., 10 mmoles) was dissolved in 20 ml. of methylene chloride. Trichloroacetyl chloride (1.1 ml., 10 mmoles) was added and the reaction stirred for 3 hours at room temperature. The reaction mixture was washed with 20 ml. of water and concentrated to yield 2-phenylthio-5-trichloroacetylpyrrole, used directly in the next step.
