Reaction Steps

HATU (152 mg, 0.40 mmol) was added in one portion to lithium 3-(4-(tert-butoxycarbonylamino)-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidine-4-carboxamido)-3-(4-chlorophenyl)propanoate (Intermediate 97) (200 mg, 0.36 mmol), dimethylamine hydrochloride (48.0 mg, 0.59 mmol) and N,N-diisopropylethylamine (0.190 mL, 1.09 mmol) in N-methyl-2-pyrrolidinone (3.0 mL) at room temperature under argon. The resulting solution was stirred overnight. Diethyl ether added to precipitate the crude product which formed as a gum. This was rinsed with Et2O and dried to give the crude gum (770 mg) which was used in subsequent reactions without further purification.
