Procedure:
Allylmagnesium bromide was prepared from 140 g (1.16 mole) of allyl bromide, 35 g (1.44 mole) of magnesium and 640 ml of ether. The product was titrated and found to be 1.2 molar in allylmagnesium bromide. To a 230 ml (0.276 mole) aliquot of the reagent was added 17.4 g (0.122 mole) of ethyl trifluoroacetate in 60 ml of dry tetrahydrofuran at a drop rate of 2-3 drops/second. The reaction temperature was held near -40° during the addition. The reaction mixture was allowed to warm to room temperature and stirred overnight. It was heated at reflux for two hours, then stirred for an additional 24 hours. The reaction mixture was poured into 300 ml of ice and 20% sulfuric acid was added to bring the pH to about 1. The phases were separated and the aqueous phase extracted with 3×70 ml of ether. The combined organic phases were dried over magnesium sulfate, filtered and the solvent evaporated. The liquid product was distilled in vacuo to give 15.2 g (70%) of 4-hydroxy-4-trifluoromethyl-1,6-heptadiene, bp 54.5-58.5° C./30 torr.

Procedure:
(R)-7-[3-tert-Butoxycarbonylamino-4-(2,4,5-trifluoro-phenyl)-butyryl]-3-trifluoromethyl-5,6,7,8-tetrahydro-imidazo[1,5-a]pyrazine-1-carboxylic acid 2a (0.15 g, 0.272 mmol) was dissolved in 10 mL of dichloromethane under stirring, and 3-aminopyridine (38.4 mg, 0.41 mmol), triethylamine (0.275 g, 2.72 mmol) and bis(2-oxo-3-oxazolidinyl)phosphinic chloride (0.138 g, 0.544 mmol) were then added to the solution. The reaction mixture was reacted at room temperature overnight and monitored by thin layer chromatography until the disappearance of the starting materials. The reaction mixture was concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography to obtain the title compound (R)-[3-oxo-3-[1-(pyridin-2-ylcarbamoyl)-3-trifluoromethyl-5,6-dihydro-8H-imidazo[1,5-a]pyrazin-7-yl]-1-(2,4,5-trifluoro-benzyl)-propyl]-carbamic acid tert-butyl ester 21a (0.1 g, yield 58.8%) as a white solid.

Procedure:
To an ice-cooled solution of phenyl dichlorophosphate (2.83 g, 0.02 mol) in dry toluene (50 mL) is added triethylamine (2.02 g, 0.02 mol) followed by nonyl alcohol (2.89 g, 0.02 mol) in dry toluene (40 mL) dropwise. The reaction mixture is stirred in an ice bath for 2 hours and then filtered. To this filtrate are added triethylamine (2.02 g, 0.02 mol) and a solution of N-[2,6-bis(1-methylethyl)phenyl]-2-[phenylmethyl]amino-acetamide (Example V) (6.40 g, 0.02 mole) and the mixture is stirred at room temperature overnight. The reaction mixture is filtered and concentrated. Flash column chromatography and crystallization from ethyl acetate affords 3.8 g of the title compound; IR (KBr); 3285, 2961, 2925, 2858, 2367, 1684, and 1508. 1H NMR (250 MHz, DMSO)δ9.22 (1 H, s), 7.44-6.92 (13 H, m), 4.50-4.30 (2 H, m), 4.30-4.00 (2 H, m), 4.00-3.60 (2 H, m), 3.10-2.80 (2 H, m), 1.70-1.40 (2 H, m), 1.4-1.18 (12 H, m), 1.18-1.00 (12 H, d, J=7 Hz), 0.98-0.76 (3 H, m).

Procedure:
1-(7-Bromoheptyl)-2,4,5-triphenylimidazole (7 g) in dry dimethylsulphoxide (15m1) was added over 20 minutes to a mixture of sodinto cyanide (0.87 g) in dimethyl-sulphoxide (25 ml ). The reaction was stirred at 40° C. for 1 hour. The cooled reaction mixture was poured into water (800 ml) and extracted with diethyl ether (4×100 ml). The extracts were combined, washed with water, dried over anhydrous magnesinm sulphate and evaporated to dryness in vacuo. Recrystallisation from dichloro-methane/hexane gave 1-(7-cyanoheptyl)-2,4,5-triphenylimidazole (3.7 g,60%) as a white solid, m.p. 93°-94°; Found: C, 82.35; H, 6.90; N, 9.96%; C29H29N3 1% CH2Cl2 requires C, 82.43; H, 6.91; N, 9.91%.

Procedure:
A mixture of [4-((2R,3R)-1-(4-fluorophenyl)-3-{[2-(4-methoxyphenyl)-2-oxoethyl]thio}-4-oxoazetidin-2-yl)phenoxy]acetic acid (0.0153 g, 0.031 mmol), tert-butyl glycyl-D-valinate hydrochloride (0.0099 g, 0.037 mmol) and N-methylmorpholine (0.010 ml, 0.091 mmol) in DCM (2 ml) was stirred at room temperature. TBTU (0.016 g, 0.050 mmol) was added and the mixture was stirred for 3.5 h. Trifluoroacetic acid (0.5 ml) was added and after 3.5 h the solvent was removed under reduced pressure. The residue was purified by preparative HPLC on a Kromasil C8-column using a gradient of 5-100% MeCN in 0.15% trifluoroacetic acid buffer as eluent. The solvent was removed under reduced pressure and 0.015 g (74%) of the title product was obtained. M/z 652.20.
