実験手順

(+/−) Tert-butyl (3-(3-(((tert-butyldimethylsilyl)oxy)methyl)-4-(oxetan-3-yl)piperazin-1-yl)-2-chloro-5-cyanophenyl)carbamate (551 mg, 1.026 mmol) was taken up in THF (5 mL) and TBAF (1.539 mL, 1.539 mmol) was added dropwise. The reaction was stirred at rt for 1 h. The reaction mixture was diluted with EtOAc and washed with water, then brine. The organic layer was dried over Na2SO4, filtered, and concentrated. The material was purified by flash column chromatography (0-100% 20% (2N NH3/MeOH)/DCM). (+/−) Tert-butyl (2-chloro-5-cyano-3-(3-(hydroxymethyl)-4-(oxetan-3-yl)piperazin-1-yl)phenyl)carbamate (416 mg) was obtained as an orange glass.
