Reaction Steps
To a solution of [(3RS,4SR)-3-[(RS)-2-(tert-butyl-dimethyl-silanyloxy)-1-(5-chloro-pyridin-2-yloxy)-ethyl]-4-(3,4-dichloro-phenyl)-pyrrolidin-1-yl]-(6-methyl-pyridazin-4-yl)-methanone 0.024 g (0.038 mmol) dissolved in THF (4 mL) was added 0.05 mL of TBAF (1.0M in THF). The reaction mixture was stirred for 30 minutes at room temperature. The mixture was diluted with ethyl acetate and washed with water and aq. sodium bicarbonate solution subsequently. The separated organic phase was dried over sodium sulfate and concentrated in vaccuo after filtration. The residue was purified by TLC (SiO2, MeOH/DCM, 1:10) yielded 18 mg (93%) of the title compound as a light yellow oil. ES-MS m/e: 509.2 (M+H+).
