At the end, reaction mixture was filtered, cooled to 3° C., and 0.1 N NaOH was added to adjust the pH to 8.5. The filtrate was washed with ethyl acetate and the aqueous layer was separated. The aqueous layer was concentrated under high vacuum at 35° C. to give a yellow precipitate. The product was purified by HP21 resin reverse phase column chromatography. Initially the column was eluted with deionized water (2 L) and latter with 10% acetonitrile:water. The fractions containing the product were collected and concentrated under reduced pressure at room temperature. The yellow solid was washed with acetone, filtered and dried.

Temperature: 100 °C
Reaction time: 0.5 h

Procedure:
At −10° C. sulfuric acid (0.46 mL) is added dropwise to a solution of methyl 3-aminobenzoate (17.2 mmol) in chlorobenzene (19 mL). After 15 min KSCN (18.2 mmol) is added portionwise over 30 min.

Procedure:
To a degassed solution of tetrakis(triphenylphosphine)palladium(0) (3 mg, 0.002 mmol) in toluene (2 mL) was added N-(t-butoxycarbonyl)-(R)-1,3,4,10b-tetrahydro-9-bromo-7-trifluoromethyl-pyrazino[2,1-a]isoindol-6(2H)-one (50 mg, 0.12 mmol). The resulting solution was degassed by exposure to vacuum and then an argon atmosphere (×3). To this solution was added 2-(tributylstannyl)furan (0.038 mL, 0.12 mmol). The resulting solution was degassed a final time and was then warmed to reflux conditions. The light yellow solution was maintained at reflux conditions for 14 h and became gray in color. The reaction was cooled, diluted with ethyl acetate, aqueous hydrogen chloride (1N), and saturated aqueous sodium chloride. The layers were separated and the aqueous layer washed with ethyl acetate. The combined organic layers were dried over sodium sulfate, filtered, and concentrated. The resulting residue was purified by radial chromatography (10-30% ethyl acetate in hexanes) to give the desired product as a clear residue (44 mg, 90%).

Procedure:
The lovastatin acid in the extract was converted into the lactone by heating it to 90° C. for 3 hours (yield of conversion was 99.2%). After cooling to room temperature, the toluene was mixed with 80 ml of water, while the pH was adjusted to pH=10 with NaOH. After separation of the layers, the toluene layer was mixed again with 80 ml of fresh water, while the pH was adjusted to pH=4 with sulfuric acid. After separation of the layers, the toluene layer was treated with 0.1 g of active coal, Norit SX ultra. Subsequently the toluene solution was filtrated and further concentrated to 15 ml by evaporation. Cooling to -10° C. resulted in crystallization. The crystals were washed with 5 ml of cold toluene, and dried under vacuum at room temperature. In these crystals no 4-acetyl lovastatin could be detected, neither by TLC nor by proton NMR.

Procedure:
To 6-chloropyridin-2-amine (20.0 g, 156 mmol) and triethylamine (23.7 mL, 171 mmol) in 100 mL toluene at 50° C. was added pivaloyl chloride (19.6 mL, 163 mmol) dropwise via syringe. The reaction mixture was allowed to stir, and eventually became a solid mass. 50 mL toluene was added. The reaction mixture was heated overnight, and cooled to ambient temperature. The reaction mixture was quenched with 400 mL 2N aq. HCl, and diluted with 300 mL EtOAc. The organic layer was washed with water, brine, dried over sodium sulfate, filtered, and concentrated to a solid. The solid was dissolved in a min. volume of hot MTBE (50° C.), and approx. 300 mL hexanes was added with swirling. On standing, crystals form, which were collected by filtration, rinsing with hexanes to give a total of N-(6-chloropyridin-2-yl)pivalamide. MS (ESI) m/z: calculated: 212.1; Observed: 213.2 (M++1).

Procedure:
A solution of compound 2 (435 g, 2.06 mol, 1 equiv) in ethanol (5 L) was treated with sodium borohydride (101.6 g, 2.68 mol, 1.3 equiv) and stirred overnight at room temperature. The reaction was concentrated under reduced pressure and the residue partitioned between 4 L of dichloromethane and 4 L of 10% aqueous hydrochloric acid. The layers were separated and the aqueous layer was extracted with dichloromethane (3×1 L). The combined organic layers were washed with saturated brine (2 L), dried over sodium sulfate and concentrated under reduced pressure. The resulting solid was dried overnight in a vacuum oven at 30° C. to give compound 3 (422 g, 96% yield) as an off-white solid.

Procedure:
Lithocholic acid (81) (7.1 g, 18.8 mmol) was dissolved in anhydrous tetrahydrofuran (60 mL) Isobutylchloroformate (2.6 g, 2.6 mL, 18.8 mmol) was added followed by the addition of triethylamine (3.84 g, 5.3 mL, 38 mmol) and dioctadecylamine (9.8 g, 18.77 g). The reaction mixture was brought to ambient temperature and allowed to stir over night.
