Reaction Conditions

Reaction Steps

To a solution of LAH (1.0 M in THF, 1.5 mL, 1.5 mmol) was added dropwise at 0° C. a solution of (αS)-α-[[(4-chlorophenyl)sulfonyl]amino]cyclohexaneacetic acid (0.50 g, 1.507 mmol) in THF (8.0 mL). After the addition was complete, the reaction mixture was allowed to warm to 25° C. After 24 hours, the reaction was quenched by sequential addition of H2O (60 μL), 15% NaOH (60 μL) and H2O (180 μL). The precipitate was filtered and washed with THF. The combined THF solution was evaporated to a clear oil which afforded a white solid after washing with hexane. This white solid was purified by flash chromatography (eluant: 1-1 hexane/ethyl acetate), washed with hexane and pumped on to afford 0.179 g (37%) of the desired product as a white solid, mp 115-118° C. Mass Spectrum (+APCI): 318 ([M+H]+). Anal: Calc'd for C14H20ClNO3S: C, 52.91; H, 6.34; N, 4.41. Found: C, 52.16; H, 6.25; N, 4.40.
