Procedure:
To a solution of (2R,4R)-1-allyloxycarbonyl-4-hydroxy-2-{2-(5-methoxymethylimidazol-1-yl)ethyl}pyrrolidine (3.63 g) in ethyl acetate (40 ml) were added successively triethylamine (2.29 ml) and methanesulfonyl chloride (1.09 ml) with stirring under ice-cooling. The mixture was stirred at the same temperature for 1 hour. To the reaction mixture was added water (20 ml). The organic layer was separated and washed with saturated aqueous sodium chloride, dried over anhydrous magnesium sulfate and evaporated in vacuo to give a residue. The residue was chromatographed on silica gel (150 g) eluting with a mixture of chloroform and methanol (19:1, V/V). The fractions containing the desired compound were collected and evaporated in vacuo to give (2R,4R)-1-allyloxycarbonyl-4-methanesulfonyloxy-2-{2(5-methoxymethylimidazol-1-yl)ethyl}pyrrolidine (3.85 g).

After 18 hours of heating, reaction mixture was cooled to room temperature and PTSA (1.0 eq) was added to complete the deprotection of the Boc group. Next, the reaction mixture was heated at 110° C. for 2 hours while stifling and cooled to room temperature. The volatiles were removed under vacuum to leave a crude solid. The crude mixture was dissolved in EtOAc (100 mL) and partitioned with 1N aqueous NaOH solution (50 mL). Organic layers were separated and the aqueous layer was washed with EtOAc (50 mL). The combined organic layers were dried over Na2SO4 and concentrated under vacuum to leave a crude solid. The solid was purified by column chromatography on silica gel (ISCO System) using 2M NH3 in MeOH/CH2Cl2 (gradient system from 0:1 to 2:8) as eluent to give the product as a solid in 36% yield.

Procedure:
3-[tert-Butyl-(2,4-dichloro-benzoyl)-amino]-5-phenyl-thiophene-2-carboxylic acid methyl ester (112 mg, 0.24 mmol) was dissolved in a mixture of THF-MeOH—H2O (3:2:1) (15 mL) and then 1.5 ml of LiOH 1N was added to it. After 3 h of stirring at room temperature, solvent was removed and then partitioned between 15 ml of H2O, 4 ml of KHSO4 5% and 15 ml of EtOAc. The organic layer was separated and the aqueous phase was washed twice with ethyl acetate (2×10 mL). The combined ethyl acetate layer was dried (MgSO4), concentrated and the residue was purified by preparative chromatography (10% MeOH/CH2Cl2) to obtain 32 mg (29%) of 3-[tert-Butyl-(2,4-dichloro-benzoyl)-amino]-5-phenyl-thiophene-2-carboxylic acid.

Procedure:
To a mixture of 0.10 g (0.23 mmole) of 4-(9-cyclopentyl-7,7-difluoro-5-methyl-6-oxo-6,7,8,9-tetrahydro-5H-pyrimido[4,5-b][1,4]diazepin-2-ylamino)-3-fluoro-benzoic acid (I-182) and 6 mL of dimethylformamide was added 0.0499 g (0.37 mmole) of 1-hydroxybenzotriazole, 0.1349 g (0.356 mmole) of 1-[bis(dimethylamino)methylene]-1H-benzotriazolium-3-oxide hexafluorophosphate and 0.0615 g (1.378 mmole) of diisopropylethylamine. The mixture was stirred for 10 minutes, then 0.0728 g (0.349 mmole) of 4-amino-1-Boc-piperidine was added. The reaction mixture was stirred for 2 hours and then concentrated under reduced pressure. The residue was dissolved in 80 mL of ethyl acetate and washed three times with 10 mL of 1M sodium hydroxide, twice with 15 mL of brine, dried, filtered and concentrated under reduced pressure. Purification by silica gel chromatography, eluting with dichloromethane-methanol (gradient, 95:5-90:10) gave 0.0906 g of 4-[4-(9-cyclopentyl-7,7-difluoro-5-methyl-6-oxo-6,7,8,9-tetrahydro-5H-pyrimido[4,5-b][1,4]diazepin-2-ylamino)-3-fluoro-benzoylamino]-piperidine-1-carboxylic acid tert-butyl ester (I-229) as a white solid.
