Procedure:
52 was prepared according to the method of Synth. Comm. 26(12), 2257-2272 (1996). To a nitrogen purged flask was charged 2-chloro-nicotinic acid (1000.0 g, 6.0 moles, 1.0 eq) followed by 9 L methylene chloride. To this was added thionyl chloride (1.4 L, 19.7 moles, 3.2 eq.) and the reaction was heated to 40° C. with vigorous stirring under nitrogen overnight. The acid chloride solution was cooled in an ice bath and methanol (3 L, 74 moles, 12 eq.) was slowly added while keeping the temperature at 20° C. The rate limiting parameter is the vigorous evolution of copious quantities of HCl gas. After the addition, HPLC analysis [Tret starting material=7.5 min, Tret 52=11 min] showed the product had formed immediately. The volatiles were removed in vacuo and the residue extracted from 10% Na2CO3 with EtOAc. The combined organics were dried (MgSO4), filtered, and concentrated to a pale yellow oil.

Procedure:
A mixture of 7-benzylamino-3-nitro-6,7,8,9-tetrahydro-5H-benzocyclohepten-5-ol (6.51 g) and potassium bisulfate (13.0 g) was heated at 210° C. for 20 minutes and suspended in a mixture of dichloromethane (150 ml), water (100 ml), and 28% ammonia solution. The suspension was filtered. The dichloromethane layer was separated, dried over magnesium sulfate, evaporated in vacuo, and chromatographed over silica gel using dichloromethane-methanol as an eluent. The first eluate afforded N-benzyl-6,7-dihydro-2-nitro-5H-benzocyclohepten-7-amine (3.11 g) as a dark brown solid.

Procedure:
To a suspension of 2,3-difluoro-6-hydroxybenzaldehyde (0.63 g) and potassium carbonate (0.83 g) in N,N-dimethyl -formamide (4 mL) was added 2-methoxyethyl bromide (0.45 mL), and the mixture was stirred at room temperature for 3 days. The reaction mixture was poured into water, and the resulting mixture was extracted with diethyl ether. The extract was washed with water and brine successively, and dried over anhydrous sodium sulfate. The solvent was removed under reduced pressure, and the residue was purified by column chromatography on silica gel (eluent: n-hexane/ethyl acetate=85/15−60/40) to give 2,3-difluoro-6-(2-methoxyethoxy)benzaldehyde (0.62 g). This material was dissolved in tetrahydrofuran (6 mL). To the solution were added water (0.6 mL) and sodium borohydride (0.12 g), and the mixture was stirred at room temperature for 1 hour. The reaction mixture was diluted with water, and the resulting mixture was extracted with ethyl acetate. The extract was washed with brine, and dried over anhydrous sodium sulfate. The solvent was removed under reduced pressure to give the title compound (0.61 g).

Procedure:
In an autoclave, a mixture of 253 mmol of 1-bromo-4-chloro-2-methyl-5-nitro-benzene [10289-13-1], 2 g of Raney nickel (60% aqueous) and 1.5 g of formamidine acetate in 102 ml of methanol is stirred under an atmosphere of hydrogen (pressure 12 bars) at 80° C. for 1 hour. The mixture is cooled to room temperature, filtered and evaporated. The residue is partitioned between aqueous saturated sodium bicarbonate-solution and tert-butyl-methyl ether. The aqueous phase is extracted with tert-butyl-methyl ether. The combined organic phases are dried over sodium sulfate, filtered and concentrated under reduced pressure. The resulting residue is purified by flash chromatography (SiO2 60 F) to afford the title compound which is identified based on the Rf value.

Procedure:
A cooled (0° C.) suspension of aluminum chloride (9.316 g; 69.87 mmol) in anh. DCE (50 ml) was treated with commercially available 1,3,5-trimethoxybenzene (7.664 g; 45.56 mmol), and stirring at 0° C., under nitrogen, was continued for 10 min. Commercially available methyl 5-chloro-5-oxopentanoate (5.000 g; 30.37 mmol) was then added, and the mixture was stirred at rt for 26 h. The resulting reaction mixture was poured onto crushed ice (150 g), and DCM (100 ml) was added. The separated aq. layer was further extracted with DCM (3×50 ml). The mixed organic layers were washed successively with water (75 ml) and brine (2×75 ml), dried over anh. MgSO4, filtered, and concentrated to dryness under reduced pressure. Purification by FC (heptane/AcOEt=10/1 to AcOEt) afforded methyl 5-oxo-5-(2,4,6-trimethoxyphenyl)pentanoate as a yellow oil. LC-MS (conditions D): tR=0.94 min.; [M+H]+: 297.13 g/mol.
