The asymmetric unit of the title compound, C15H17NO2, contains two independent mol­ecules in which the dihedral angles between the pyrrole and benzene rings are 42.43 (9) and 45.70 (9)°. In both mol­ecules, the but­oxy chains are disordered over two sets of sites, with occupancy ratios of 0.701 (7):0.299 (7) and 0.869 (4):0.131 (4). Each mol­ecule forms a dimer with an inversion-related mol­ecule, through a pair of N—H⋯O hydrogen bonds. Weak C—H⋯O inter­actions link these dimers in the crystal structure.
