Reaction Steps

10-Bromo-9-fluoro-3-iodo-5,6-dihydroimidazo[1,2-d][1,4]benzoxazepine-2-carboxamide (0.1 g) was reacted with 2-methyl-1-[4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyrazol-1-yl]propan-2-ol similar to as described in Example 5 and triturated from water followed by methanol to give 100 mg of 10-bromo-9-fluoro-3-[1-(2-hydroxy-2-methyl-propyl)pyrazol-4-yl]-5,6-dihydroimidazo[1,2-d][1,4]benzoxazepine-2-carboxamide. This intermediate was reacted with 2-Methyl-3-butyne-ol via similar to as described in Procedure E to afford 18.1 mg of 9-fluoro-10-(3-hydroxy-3-methyl-but-1-ynyl)-3-[1-(2-hydroxy-2-methyl-propyl)pyrazol-4-yl]-5,6-dihydroimidazo[1,2-d][1,4]benzoxazepine-2-carboxamide following reverse phase hplc purification.
