Participants

Reaction Steps

A solution of (R)-3-amino-3-(5-bromo-2-fluoro-phenyl)-2-methyl-butan-2-ol (2.91 g, 10.5 mmol) in dichloromethane (35 ml) was stirred intensively together with a saturated sodium hydrogen-carbonate solution (30 ml) at 0° C. Chloroacetyl chloride (0.92 ml, 11.6 ml) was added and stirring continued for 1 hour at 0° C. For the workup, the aqueous layer was separated and extracted with dichloromethane. The combined organic layers were dried over sodium sulfate, then evaporated. The title compound was obtained as a white solid (3.5 g, 94% of theory) which was used in the next step without further purification. Mass (calculated) C13H16BrClFNO2 [352.629]; (found) [M+H]+=352, [M+2-H]+=354.
