HATU (0.418 g, 1.10 mmol) was added in one portion to 4-(tert-butoxycarbonylamino)-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidine-4-carboxylic acid (Intermediate 1) (0.361 g, 1.0 mmol), 1-(4-chlorophenyl)-2-(thiazol-2-yl)ethanamine (Intermediate 95) (0.318 g, 1.00 mmol) and N,N-diisopropylethylamine (0.348 mL, 2.00 mmol) in N-methyl-2-pyrrolidinone (5.0 mL) at room temperature under argon. The resulting solution was stirred overnight. Et2O was added to precipitate the rude product, which was filtered, washed plentifully with Et2O and dried in vacuo to give tert-butyl 4-(1-(4-chlorophenyl)-2-(thiazol-2-yl)ethylcarbamoyl)-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidin-4-ylcarbamate (0.550 g, 94%).
