Procedure:
n-BuLi (1.3 ml, 2.09 mmol) is stirred in THF (4 ml), under N2, and cooled to −72° C. 1,4-dimethyl-1H-pyrazole (170 mg, 2.04 mmol, in THF, 1 ml) is added slowly, stirred for 5 min. then allowed to warm to ambient temp. and stirred for 45 min. The mixture is cooled to −72° C. and a zinc chloride solution (4.3 ml, 2.14 mmol, 0.5 M in toluene) added, warmed to ambient temp. and treated with 8-(1-ethyl-propyl)-3-iodo-2,6-dimethyl-imidazo[1,2-b]pyridazine and PdCl2(dppf)-CH2Cl2 complex (Aldrich, 40 mg, 0.05 mmol). The mixture is heated to 65° C. overnight, cooled to ambient temp., added to water and extracted twice with EtOAc. The combined organic extracts were washed with brine, dried over Na2SO4, filtered and concentrated. The crude product is purified by chromatography using a hexane-ethyl acetate gradient (100% hexane to 50% ethyl acetate in hexane) to elute the product. The title compound is obtained (0.7% yield).

Procedure:
To a mixture of 2,3-dichloropyridine (92.60 g, 0.629 mol) and 3-chloropyrazole (i.e. the product of Step B) (64.44 g, 0.629 mol) in N,N-dimethylformamide (400 mL) was added potassium, carbonate (147.78 g, 1.06 mol), and the reaction mixture was then heated to 100° C. for 36 hours. The reaction mixture was cooled to room temperature and slowly poured into ice water. The precipitated solids were altered and washed with water.

Procedure:
Using the same general procedure as for the preparation of of 4-bromo-2-t-butyl-1-(2-tetrahydropyranoxy)benzene (Compound H), but instead using 12.56 g (40.9 mmol) of 2-(1-adamantyl)-5-bromophenol (Compound G), 1.03 g (4.1 nunol) of pyridinium p-toluenesulfonate, 5.16 g (5.6 ml, 61.3 mmol) of 3,4-dihydro-2H-pyran and 50 ml of dichloromethane produced a clear, orange solution. During aqueous workup, the organic phase was washed with 3×150 ml-portions of sat. aqueous NaHCO3 solution to produce a light yellow solid. Purification by flash chromatography (silica, 3% ethyl acetate in hexane) yielded the title compound as a white solid.
