Reaction Steps

Prepared according to the procedure outlined in Example 1 substituting 3-methyl-azetidin-3-ol trifluoroacetate for pyrrolidine, Boc-D-cyclopropyl glycine for Boc-D-tert-leucine, and 2-(1-ethyl-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. Trifluoroacetic acid was used instead of hydrochloric acid for all N-Boc deprotection steps. MS: (M+H)+=424.
