Procedure:
To a solution of methylamine (2.0 M solution in tetrahydrofuran, 30 ml) in N,N-dimethylformamide (30 ml), 3-chlorobenzyl chloride (2.5 ml) was added, and the mixture was stirred at room temperature for 4.5 hours. Water was added to the reaction solution, followed by extraction with ethyl acetate. The extract was washed with water and saturated saline in this order and then dried over anhydrous sodium sulfate. The solvent was distilled off under reduced pressure to obtain a crude product of the title compound, which was used in the next reaction without being purified.

Procedure:
4.8 g (0.015 mol) of 5-hydroxy-3-(tert-butyl)-1-(2,4,6-trichlorophenyl)-1H-1,2,4-triazole was added to 20 ml of phosphorus oxychloride, and stirred under reflux for 24 hours. The reaction mixture was cooled, and excess phosphorus oxychloride was distilled off under reduced pressure. To the residue, 100 ml of dichloromethane was added, and the mixture was washed with water. Then, the dichloromethane layer was dried, and the solvent was distilled off. The residue thereby obtained was purified by silica gel column chromatography to obtain 4.3 g (yield: 84.3%) of the desired compound as white needle like crystals. Melting point 98°-98.5° C.

Procedure:
Methyl 3-bromo-1-naphthalenecarboxylate (1 eq.) and 2-ethenyl-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (1 eq.) were combined in a 2:1 (v/v) mixture of DMF:n-PrOH (0.1 M). To this solution was first added Pd(PPh3)2Br2 (0.05 eq.) followed by 2 N aq. Na2CO3 (2 eq.). The biphasic suspension was evacuated and back-filled three times with nitrogen before it was heated at 90° C. for 8 h. The now black suspension was cooled to RT, diluted with water and extracted with 1:1 (v/v) hexanes:ether. The combined organic extracts were then washed further with 1 N aq. NaOH, 10% aq. HCl, water and brine. This was then dried over Na2SO4 and filtered through a pad of silica gel. Concentration of the filtrate in vacuo afforded the crude title compound as a golden yellow oil.
