(1-Methylpyrrol-2-yl)-(3-nitrophenyl)methanone → 3-(1-Methylpyrrol-2-ylmethyl)nitrobenzene

Participants

Reaction Steps

A mixture of 2-(3-nitrobenzoyl)-1-methylpyrrole (5.0 g, 21.7 mmol) [prepared as in Example 8, Step (a)], zinc iodide (10.38 g, 32.5 mmol), sodium cyanoborohydride (10.22 g, 162.7 mmol), and 1,2-dichloroethane (300 ml) was refluxed for 16 h. The reaction mixture was cooled to room temperature, filtered through Celite®, and then concentrated to dryness. Purification of the residue on a Florisil® column (hexane-acetone, 98:1) gave 3-(1-methylpyrrol-2-ylmethyl)nitrobenzene (3.55 g, 75%) as a solid. ##STR44##
