Reaction Steps
Prepared according to the procedure outlined in Example 1 substituting thiomorpholine-1,1-dioxide 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 in step 2 was achieved using 2,2,2-trifluoroethanol in a microwave reactor. SEM deprotection in step 4 was achieved using CsF in refluxing acetonitrile. MS: (M+H)+=458.
