Participants

Reaction Steps

In a 50 mL round-bottomed flask 1,1-dimethylethyl[(1R)-2-({6-[(2,6-dimethylphenyl)oxy]-3-pyridinyl}amino)-1-methyl-2-oxoethyl]carbamate (Intermediate 43, 282 mg) was dissolved in dichloromethane (2 mL) to give a yellow solution. Trifluoroacetic acid (2 mL, 26.0 mmol) was added. The reaction mixture was stirred at room temperature. After 20 min, the solvent was evaporated under vacuum affording a yellow oil that was charged on a 5 g SCX cartridge. It was then flushed with 25 mL of MeOH followed by 25 mL of 2M solution of ammonia in MeOH. The ammonia eluate was evaporated under vacuum to afford the title compound as a yellow oil which solidified (173.8 mg).
