Dichloromethane → Tert-butyl (2S,3R)-4-((S)-2,2-dimethyl-6-neopentyl-1,2,3,4-tetrahydroquinolin-4-ylamino)-1-(3-fluorophenyl)-3-hydroxybutan-2-ylcarbamate

참여 물질

반응 단계

To a solution of tert-butyl (2S,3R)-3-(tert-butyldimethylsilyloxy)-4-((S)-2,2-dimethyl-6-neopentyl-1,2,3,4-tetrahydroquinolin-4-ylamino)-1-(3-fluorophenyl)butan-2-ylcarbamate (0.231 g, 0.360 mmol) in DCM (1.20 ml, 0.360 mmol) was added tetrabutylammonium fluoride (1.44 ml, 1.44 mmol). The resulting solution was stirred overnight. The mixture was transferred to a sep. funnel containing EtOAc and H2O. The aqueous layer was washed 4× with EtOAc. The proganic layers were combined, dried over MgSO4, filtered and concentrated. The crude mixture was purified by the MPLC. MS m/z: 528 (M+1).
