Reaction Steps

Compound 86A was prepared in a similar manner to the synthesis of compound 34D by substituting compound 34C and 4-(hydroxymethyl)phenylboronic acid with 3-chloropyrazine-2-carbonitrile and 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenol, respectively: 1H NMR (DMSO-d6): δ 10.14 (s, 1H), 8.95 (d, J=2.45 Hz, 1H), 8.73 (d, J=2.45 Hz, 1H), 7.83-7.85 (m, 2H), 6.95-6.99 (m, 2H). ESI (+)/MS: 211 (M+H)+.
