title: 1-tert-Butyl 2-ethyl 5-chloro-3-(2-furo-yl)-1H-indole-1,2-dicarboxyl-ate.
abstract: In the title compound, C21H20ClNO6, the furan moiety is located above the mean plane of the indole ring and displays rotational disorder (i.e. rotation through 180°); the site occupancy of the major component is 0.809 (6). In the crystal, C-H⋯O inter-actions link the mol-ecules into chains which run parallel to the b axis.
