실험 절차

(S)-tert-Butyl 4-(1-cyano-2-(4-(1-oxoisoindolin-5-yl)phenyl)ethylcarbamoyl)tetrahydro-2H-pyran-4-ylcarbamate (Example 15, step (ii), 160 mg) was stirred in formic acid (0.5 mL) at 50° C. for 20 min. The reaction mixture was cooled to room temperature and the mixture diluted with water (20 mL). The solution was basified with 0.880 ammonia and extracted into ethyl acetate (100 mL). The extract was dried over magnesium sulfate and concentrated. The crude product was purified by chromatography on silica using methanol/ethyl acetate (1/9) to afford the titled compound as a solid (70 mg).
