実験手順

(S)-3,5-dichloro-4-(2-(3-(cyclopropylmethoxy)-4-(difluoromethoxy)phenyl)-2-hydroxyethyl)pyridine 1-oxide (Compound 7, 60 mg, 0.143 mmol), 2-(6-(tert-butoxycarbonylamino)-1-oxoisoindolin-2-yl)acetic acid (65.6 mg, 0.214 mmol), DMAP (20.93 mg, 0.171 mmol), and EDC (82 mg, 0.428 mmol) were dissolved in DMF (5 ml). The reaction was stirred at RT overnight. The reaction mixture was diluted with water, and the precipitate was washed with water, dissolved in EtOAc and extracted with HCl 1N, Na2CO3 sat. sol. and brine. The organic phase was dried over Na2SO4 and concentrated under vacuum to give (S)-4-(2-(2-(6-(tert-butoxycarbonylamino)-1-oxoisoindolin-2-yl)acetoxy)-2-(3-(cyclopropylmethoxy)-4-(difluoromethoxy)phenyl)ethyl)-3,5-dichloropyridine 1-oxide (70 mg, 0.099 mmol, 69% yield). MS/ESI+ 306.12 [MH]+
