Water → 2-[(4-Bromo-2-fluoro-phenyl)methyl]-6-phenyl-thiazinane 1,1-dioxide

Participants

Reaction Steps

To a solution of 6-phenyl-1,2-thiazinane 1,1-dioxide (300 mg, 1.42 mmol) and 4-bromo-1-(bromomethyl)-2-fluorobenzene (456 mg, 1.7 mmol) in N,N-dimethylacetamide (5 mL) at 0° C. was added sodium hydride (60% in mineral oil) (68 mg, 1.85 mmol) and the reaction was stirred at room temperature for 2 hours. Water was added and the reaction was diluted with EtOAc, washed with brine, dried with MgSO4, filtered and purified by silica gel column chromatography (0-60% EtOAc/heptane) to give 2-(4-bromo-2-fluorobenzyl)-6-phenyl-1,2-thiazinane 1,1-dioxide (396 mg, 70% yield). LCMS (ESI), m/z, 398 [M+H]+.
