実験手順
To (S)-tert-butyl 4-(1-cyano-2-(4′-(ethylsulfonyl)biphenyl-4-yl)ethylcarbamoyl)tetrahydro-2H-pyran-4-ylcarbamate (Example 1, step (v(ii)), 920 mg) was added formic acid (3 mL) and the mixture heated to 50° C. for 30 min. The mixture was evaporated to dryness, dissolved in methanol (9 mL) and purified on reverse phase HPLC eluting with 25 to 95% methanol in 0.1% TFA on a Waters SunFire column. The material was converted to free base by evaporating the relevant fractions, dissolving in dichloromethane (20 mL) and shaking with saturated sodium bicarbonate solution (20 mL). The dichloromethane was dried and evaporated to afford the titled compound as a solid (397 mg).
