Product 1

HCID 533863112-(1-Methyl-1H-pyrazol-4-yl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid [(R)-2-(3-cyano-azetidin-1-yl)-1-cyclopropyl-2-oxo-ethyl]-amide

Procedure

Prepared according to the procedure outlined in Example 1 substituting 3-cyanoazetidine hydrochloride for pyrrolidine, Boc-D-cyclopropyl glycine for Boc-D-tert-leucine, and 2-(1-methyl-1H-pyrazol-4-yl)-5-((2-(trimethylsilyl)ethoxy)methyl)-5H-pyrrolo[3,2-b]pyrazine-7-carboxylic acid for 2-cyclopropyl-5-(2-trimethylsilanyl-ethoxymethyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid. N-Boc deprotection was achieved using 2,2,2-trifluoroethanol in a microwave reactor. MS: (M+H)+=405.
