Lithium Hydroxide → lithium 3-(4-(tert-butoxycarbonylamino)-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidine-4-carboxamido)-3-(4-chlorophenyl)propanoate

Participants

Reaction Steps

Lithium hydroxide (1.436 mL, 2.87 mmol) 2N in water was added to a stirred suspension of methyl 3-(4-(tert-butoxycarbonylamino)-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidine-4-carboxamido)-3-(4-chlorophenyl)propanoate (Intermediate 35) (400 mg, 0.72 mmol) in THF (40 mL) at room temperature. The resulting suspension quickly went into solution and was then stirred at RT overnight. The following morning a white precipitate had formed. This was filtered and dried in vacuo to give lithium 3-(4-(tert-butoxycarbonylamino)-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidine-4-carboxamido)-3-(4-chlorophenyl)propanoate (396 mg, 100%).
