Compound BE was prepared by a method analogous to that described in Example 1 by substituting 1-methyl-1H-indol-5-amine for 1H-indol-5-amine in the reaction with Intermediate BA to prepare 6-bromo-1-(1-methyl-1H-indol-5-yl)-1H-imidazo[4,5-b]pyrazin-2(3H)-one. In a procedure similar to that used to synthesize Compound D, 4-hydroxyphenylboronic acid was substituted for 3,4,5-trimethoxyphenylboronic acid and 6-bromo-1-(1-methyl-1H-indol-5-yl)-1H-imidazo[4,5-b]pyrazin-2(3H)-one was substituted for 6-bromo-1-(1H-indol-5-yl)-1H-imidazo[4,5-b]pyrazin-2(3H)-one to obtain the title compound. 2.2 mg recovered. HPLC retention time: 2.18 minutes. MS ESI (m/z): 358.2 (M+H)+, calc. 357.
