ABSTRACT
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 = 0.006â
(1)â
Å]. The pyran ring is in an envelope conformation [puckering parameters Q = 0.115â
(2)â
Å, θ = 77.5â
(10), Ï = 172.9â
(10)°]. The pyran and phenyl rings are approximately perpendicular, making a dihedral angle of -76.4â
(2)°. The crystal packing is stabilized by inter-molecular N-Hâ¯O hydrogen bonds, with the sulfone O atoms acting as acceptors.
