In the title compound, C(14)H(11)BrN(2)O(3)S, the 2,3-dihydro-thio-phene ring is almost planar [maximum deviation = 0.006 (1) Å]. The pyran ring is in an envelope conformation [puckering parameters Q = 0.115 (2) Å, θ = 77.5 (10), ϕ = 172.9 (10)°]. The pyran and phenyl rings are approximately perpendicular, making a dihedral angle of -76.4 (2)°. The crystal packing is stabilized by inter-molecular N-H⋯O hydrogen bonds, with the sulfone O atoms acting as acceptors.
