6-(Trifluoromethyl)-3-pyridinol Use and Manufacturing

Step 1: tert-butyl (cis-3-(((6-(trifluoromethyl)pyridin-3-yl)oxy)methyl)-cyclobutyl)carbamate Diethyl azodicarboxylate (13 mL of 40% w/w, 28 mmol) was added dropwise to a solution of tert-butyl (cis-3-(hydroxymethyl)-cyclobutyl)carbamate (4.699 g, 23.35 mmol), General procedure: A mixture of (75)-2-((cis-3-(hydroxymethyl)cy- clobutyl)amino)-7-isopropyl-4, 8-dimethyl-7, 8-dihydropte- ridin-6(5H)-one (1 equiv), triphenyl phosphine (2.1 equiv), and the heterocycle (hydroxy heterocycle, pyrazole, or imidazole derivative; 1.6 equiv) was taken into THF (25 vol equiv). Diethylazodicarboxylate (2.1 equiv) was added to the mixture dropwise at room temperature then heated to 50 C. for 2 hours. The crude products were purified by preparative reverse phase HPLC (C18 colunm) eluting with 10-95% acetonitrile/water (0.5 mMHC1) to provide theproducts described in Table 26.Step 1: tert-Butyl ((trans-4-(((6-(trifluoromethyl)pyridin-3-yl)oxy)methyl)cyclohexyl)methyl)carbamate Diisopropyl azodicarboxylate (500 uL, 2.59 mmol) was added dropwise to a solution of tert-butyl ((trans-4-(hydroxymethyl)cyclohexyl)methyl)carbamate (525 mg, 2.16 mmol),
