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 1-methyl-1H-pyrazol-3-amine give 3-(4,4-difluorocyclohexyl)-2-(5,5-dioxo-5,10-dihydrophenothiazin-2-yl)-N-(1-methyl-1H-pyrazol-3-yl)propionamide.
