Reaction Steps

97.5 g (1.2 eq) of methoxyamine hydrochloride are added to a solution of 148.8 g (0.97 mol) of methyl pyrrol-2-ylglyoxylate (prepared by a method similar to that described by B. Lindstrom et al., Acta Chem. Scand. 27 (1973), 7) in 1 l of methanol, and the solution is refluxed for 2.5 hours. After evaporation in a rotary evaporator, the residue is taken up in ethyl acetate and the solution is washed with water, dried and evaporated down. 81 g (46%) of the pyrrole remained in the form of an oil.
