<i>tert</i>-Butyl [(4-fluoro-3-isopropoxyisoxazol-5-yl)methyl](phenylsulfonyl)carbamate
The title compound, C<sub>18</sub>H<sub>23</sub>FN<sub>2</sub>O<sub>6</sub>S, a new derivative of a fluoro-isoxazole containing sulfonamide functionality has been structurally characterized. The C-S-N-C<sub>ipr</sub> and C-S-N-C<sub>carb</sub> (ipr = 3-isopropoxyisoxazole, carb = carbamate) torsion angles are 111.1 (3)° and -70.0 (4)°, respectively. The sulfonamide functional group of this structure features S=O bond lengths of 1.403 (3) and 1.433 (3) Å, an S-N bond length of 1.672 (4) Å, and an S-C bond length of 1.753 (4) Å. The crystal packing features non-classical C-H⋯O hydrogen-bond inter-actions, with the carbonyl atom acting as a bifurcated acceptor, resulting in an <i>R</i> <sup>1</sup> <sub>2</sub>(8) ring.
