الإجراء التجريبي

Analogously to Example 36 and Example 44, tert-butyl 2-ethoxycarbonylmethyl-5,5-dioxo-5H-phenothiazine-10-carboxylate, 1,1-difluoro-4-iodomethylcyclohexane (prepared from commercially available ethyl 4,4-difluorocyclohexanecarboxylate analogously to the synthesis of the iodide described in Example 40) and 5-methoxy-thiazolo[5,4-b]pyridin-2-ylamine give 3-(4,4-difluorocyclohexyl)-2-(5,5-dioxo-5,10-dihydrophenothiazin-2-yl)-N-(5-methoxythiazolo[5,4-b]pyridin-2-yl)propionamide.
