Process for making benzoxazepin compounds

A process for preparing (2-(4-(2-(1-isopropyl-3-methyl-1H-1,2,4-triazol-5-yl)-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepin-9-yl)-1H-pyrazol-1-yl)-2-methylpropanamide I, having the structure:

• and stereoisomers, geometric isomers, tautomers, and pharmaceutically acceptable salts thereof, comprising:
• (a) reacting IV and 4,4,4′,4′,5,5,5′,5′-octamethyl-2,2′-bi(1,3,2-dioxaborolane) to form 22
• (b) reacting 22, a palladium catalyst, and III to form 23
• (c) reacting 23 with an aqueous basic reagent to form II
• and
• (d) reacting II with an acyl activating reagent, followed by ammonia to give I.
