Procedure:
Compound 2 was prepared according to the procedure of A. Kalir et al. [Isr. J. Chem. 5: 129-136 (1967)]. To a 100-mL round bottom flask, 6.674 g of powdered 3-methoxy-2-nitrobenzaldehyde (98%, Aldrich) (36.87 mmol), 2.1 mL of nitromethane (39 mmol), and 15.5 mL of methanol were added. This suspension was cooled to approximately 5° C., and 5.6 mL of 9.5N aqueous sodium hydroxide (53 mmol) was added. An additional 1 mL of nitromethane, 9.5N aqueous sodium hydroxide, and methanol was added. The reaction mixture was stirred for 1 hr at approximately 5° C. Over the course of the hour an additional 5 mL of methanol was added. After 1 hr the precipitate was dissolved in 25 mL of water. This solution was added to 20 mL of 10% aqueous hydrochloric acid. The resulting precipitate was extracted with three 100-mL portions, one 50-mL portion, and finally one 25-mL portion of diethyl ether. The ether extracts were combined, dried with MgSO4, and filtered. The ether was removed by rotary evaporation and the residue was refluxed for 5 min in 31 mL of acetic anhydride and 3.566 g of anhydrous sodium acetate. The solution was allowed to cool and then was diluted with water. The precipitate was collected. Recrystallization from hot methanol with a recovery of a second crop of crystals from the mother liquor yielded 5.891 g (71%) of 2 as yellow crystals: 1H NMR (CDCl3) δ 3.94 (s, 3H, OCH3), 7.19 (d, 2H, J=8.3 Hz), 7.50 (m, 2H), 7.85 (d, 1H, J=13.7 Hz).

Procedure:
5.1 g of triethylamine was added to a stirred mixture of 5.0 g of 33A and 100 mL of toluene, then 1.9 g of diphenylphosphoryl azide was added and over two hours the mixture was heated to and held at reflux temperature. The resulting mixture was poured into 110 mL of 10% w:v aqueous ice-cold potassium hydroxide solution. Two liquid phases resulted and were separated. The aqueous phase was acidified with 12N hydrochloric acid, and extracted with ethyl acetate. The extract was washed with water, then with brine, dried (MgSO4) and stipped of solvent. The residue was recrystallized from ethyl acetate/hexane to give 2-(7-chloro-2,3-dihydro-2-methyl-4-benzofuranyl)-5-methyl-2H-1,2,4-triazol-3(4H)-one (33B), as a colorless solid, m.p.: 208°-209° C.

Procedure:
2,2-bis(hydroxymethyl)propane-1,3-diol (10.55 g, 77 mmole) was taken up in dry pyridine (100 mL). Tert-butyldiphenylsilyl chloride (4.26 g, 15 mmole, 0.2 eq) was then added dropwise over 10 minutes to the pyridine solution at ambient temperature. The reaction mixture was stirred at ambient temperature for 24 hours. TLC (EtOAc) indicated that the reaction was complete. The reaction was diluted with EtOAc (250 mL), washed with 10% HCl (3×200 mL). The organic layer was dried over sodium sulfate and then concentrated in vacuo to afford a thick pale yellow oil. Column chromatography on silica gel (200 g), eluted with EtOAC followed by concentration of the appropriate fractions gave 5.01 g of the title compound as a clear colorless oil which solidified very slowly upon standing (86%). 1H NMR (300 MHz, CDCl3) δ 7.65 (m, 4H), 7.42 (m, 6H), 3.74 (s, 6H), 3.66 (s, 2H), 1.08 (s, 9H); MS (70 eV, EI) 392 (M+NH4)+.

Procedure:
N-butyl lithium (150.6 ml, 241 mmol) is added dropwise to ether (100 ml) at −20° C. under N2. 3-Bromothianaphthene (10.5 ml, 80.3 mmol) is dissolved in ether (50 ml) and also added dropwise to the chilled solution, stirring cold for 0.5 h. DMF (16.3 ml, 210 mmol) is dissolved in ether (75 ml) and added dropwise, and the solution stirred an additional 15 h at −20° C. The reaction is quenched onto ice (300 g) in 10% H2SO4 (200 ml) and stirred until both layers turn yellow in color. The resulting slurry is filtered, and the cake is allowed to dry in the air stream, affording 1-benzothiophene-2,3-dicarbaldehyde (C180) as a yellow solid (60% yield). HRMS (FAB) calculated for C10H6O2S+H: 191.0167, found 191.0172 (M+H).
