Reaction Steps

To a stirred solution of 4-hydroxy-3-methoxymethoxymethyl-piperidine-1-carboxylic acid tert-butyl ester (0.4 mmol, 0.111 g) in 3 mL of THF was added 60% NaH in mineral oil (2.0 mmol, 0.05 g) at room temperature. The mixture was stirred for 10 mins, then a solution of 3-butyl-6-chloro-4-(4-cyclohexyloxy-phenyl)-pyridazine (Example 14, 0.2 mmol, 0.07 g) in THF was added. The mixture was refluxed for 1 h, then, stirred at room temperature overnight. The mixture was quenched with water, extracted with ethyl acetate, the organic layer was washed with brine, dried (Na2SO4), filtered and concentrated under reduced pressure, the resulting residue was chromatographed using 10% ethyl acetate in hexane to provide 4-[6-butyl-5-(4-cyclohexyloxy-phenyl)-pyridazin-3-yloxy]-3-methoxymethoxymethyl-piperidine-1-carboxylic acid tert-butyl ester.
