Procedure:
A solution of t-butyl ester 234e (179 mg, 0.35 mmol) in dry CH2Cl2 (3 ml) was cooled to 0° C. and treated with trifluoroacetic acid (2 ml). The resulting solution was stirred at 0° C. for 30 min and then at room temperature for 2 h. The solution was concentrated, the residue taken up in dry CH2Cl2 (5 ml) and the mixture again concentrated. This process was repeated once again with more CH2Cl2 (5 ml). The residue obtained was crystallized in diethyl ether. The precipitate was collected and purified on silica gel column (5% methanol in CH2Cl2) which afforded compound 235e as a white solid (111 mg, 70%): mp 142° C.

Procedure:
A solution of trimethylaluminium in toluene (2M, 0.6 mL, 1.2 mmol) was slowly added to a suspension of ammonium chloride (64 mg, 12 mmol) in dry toluene (5 mL) at 0° C. under nitrogen. The resulting mixture was warmed to 25° C. and stirred for 3 hours until gas evolution had ceased. Then, N-triphenylmethyl-4-(trans-2-cyano-cyclopropyl)imidazole (200 mg, 0.53 mmol) in dry toluene (10 mL) was added and the reaction mixture was heated to 80° C. for 18 hours under nitrogen, slowly poured into a slurry of silica gel (15 g) in chloroform (50 mL), and stirred for 10 minutes. The silica was filtered and washed with methanol. The combined solvent mixture was concentrated under vacuum and the residue was purified on a silica gel column using 85/15/5 (v/v/v) methylene chloride/methanol/ammonium hydroxide as the eluent to give a white solid (140 mg, 68% yield).

Procedure:
1.6M n-Butyllithium (1.19 ml, 1.90 mmol) was added to dry THF (10 ml) containing diisopropylamine (0.266 ml, 1.90 mmol) under Ar at 0° C. After 15 mins, the mixture was cooled to -78° C., and 3-acetyl-1-methyl-1H-indole (0.300 g, 1.73 mmol) in dry THF (5 ml) was added slowly. The resulting mixture was left at -78° C. for 1 h, before pyridine-4-carboxaldehyde (0.165 ml, 1.73 mmol) was added. The reaction mixture was then left at -78° C. for 1 h, before being allowed to warm to 0° C., whereupon chlorotrimethylsilane (0.439 ml, 3.46 mmol) was added. The mixture was then allowed to warm to room temp and stirred for 1 h, before being evaporated under reduced pressure and partitioned between dichloromethane and water. The organic layer was then dried (Na2SO4) and evaporated under reduced pressure to give a pale yellow solid which was purified by silica-gel chromatography (EtOAc as eluant) to give the title compound as a yellow solid (0.300 g, 51%).

Procedure:
Under an argon atmosphere, to a stirring solution of N,5-dimethoxy-N-methyl-4-oxo-1-phenyl-1,4-dihydropyridazine-3-carboxamide (20 g) in tetrahydrofuran (1 L) was added dropwise, under cooling at −69° C., methyl magnesium bromide solution (1 M in THF, 138 mL). After stirring at −69° C. for 1.5 hr, a saturated aqueous ammonium chloride solution was added. Thereafter, the mixture was warmed to room temperature in 1.5 hr, and the reaction mixture was partitioned. The organic layer was washed with saturated brine, and dried over anhydrous magnesium sulfate. The aqueous layer was extracted with ethyl acetate, and the obtained extract was dried over anhydrous magnesium sulfate. The organic layer and the extract were combined, and concentrated under reduced pressure to dryness. The residue was purified by silica gel column chromatography (ethyl acetate/methanol) to give the title compound (13.22 g) as a pale-yellow solid.

Procedure:
A 4-L reactor equipped with a mechanical stirrer, under nitrogen, was charged with (3aR,4R,5R,6aS)-4-formyl-2-oxohexahydro-2H-cyclopenta[b]furan-5-yl benzoate (Cayman Chemical Catalog #70030, 99.2 g, 0.362 mol) in dichloromethane and lithium chloride (16.7 g, 0.398 mol) dissolved in tetrahydrofuran. Dimethyl 2-oxo-3-phenoxypropylphosphonate (102.7 g, 0.398 mol) is added neat and rinsed with dichloromethane (50 mL). Some lithium chloride precipitated from solution when the THF and DCM solutions were mixed. The mixture was stirred under nitrogen and cooled to −20° C. After adding the phosphonate and subsequent stirring and cooling, the precipitated lithium chloride dissolved. After stirring for 2.5 hours, triethylamine (40.2 g, 0.398 mol) was added neat via addition funnel and the temperature was held at −5° C. and stirred at this temperature for 19 hours. The temperature was adjusted to 0° C. and treated with 5% aqueous citric acid and the layers were separated. The organic layer was dried over magnesium sulfate and filtered. The crude product was purified on silica gel, eluted with ethyl acetate-hexanes (1:1). The desired product precipitated from the product-rich fractions as a white fluffy solid. After further purification of mixed fractions, all the purified product crystallized from MTBE to afford the title intermediate (74.4 g, 50.6%) as a white solid.
