Procedure:
140 grams of the ethylene glycal ketal of 2-acetyl-9-(1-methyl-4-piperidyl)-9-thioxanthenol (MP 206-208 degrees Centigrade) were heated for two hours under reflux with a mixture of 1500 milliliters of propionic acid and 100 grams of 2-sulfobenzoic acid anhydride. Thereafter the mixture was evaporated in vacuum, the residue dissolved in water and made alkaline. The base which separated out was extracted with ether, the ether phase dried over anhydrous potassium carbonate and evaporated until beginning crystallization. The crystals were sucked off and dried. - 50 grams of 4-(2-acetyl-9-thioxanthenylidene)-1-methyl-piperidine were obtained melting at 125-127 degrees Centigrade.

Procedure:
A solution of N1-[2-(4-amino-2-butyl-1H-imidazo[4,5-c][1,5]naphthyridin-1-yl)ethyl]-3,5-di-(1,1-dimethylethyl)-4-hydroxybenzamide (0.1 g, 0.19 mmol) in trifluoroacetic acid (15 mL) and platinum oxide (0.1 g) were combined and hydrogenated overnight on a Parr apparatus. The reaction mixture was filtered to remove the catalyst. The filtrate was concentrated under vacuum. The residue was dissolved in dichloromethane. The dichloromethane solution was washed twice with 10% sodium hydroxide and with brine, dried and then concentrated under vacuum to provide crude product. This material was purified by chromatography eluting with 10% methanol in dichloromethane. The resulting oil was triturated with acetonitrile to provide 0.05 g of N1-[2-(4-amino-2-butyl-6,7,8,9-tetrahydro-1H-imidazo[4,5-c][1,5]naphthyridin-1-yl)ethyl]-3,5-di-(1,1-dimethylethyl)-4-hydroxybenzamide as a white powder, m.p. 208-210° C.

Procedure:
To a solution of 5.00 g of 2,2,2-trifluoro-5′-(trifluoromethyl)acetophenone in 1 mL of acetic acid and 6 mL of concentrated sulfuric acid, 3.54 g of 1,3-dibromo-5,5-dimethylhydantoin was added and the resultant mixture was stirred at 35° C. for 3.5 hours. After the completion of the reaction, the reaction mixture was charged into 60 mL of ice water and the resultant mixture was extracted with chloroform (30 mL×2). The organic phase was washed with a saturated sodium hydrogen carbonate aqueous solution (50 mL×1) and then dehydrated and dried over saturated saline and anhydrous magnesium sulfate in this order, and the solvent was distilled off under reduced pressure. The resultant residue was dissolved in 20 mL of hexane and an insoluble substance was filtered off, followed by distilling off the solvent under reduced pressure to obtain 6.50 g of the objective substance as a yellow oily substance. This substance was used in the next process as it was without being further purified.

Procedure:
To (R)-tert-butyl 2-(2,5-difluorophenyl)pyrrolidine-1-carboxylate (23.9 g, 84.4 mmol) was added 4N HCl in dioxane (56.2 mL). After stirring at ambient temperature for 2 hours, ether (200 mL) was added and the mixture was stirred for 10 minutes. The resulting slurry was filtered, yielding the title compound hydrochloride salt as a white solid (17.2 g). To obtain the free base, the HCl salt product was dispersed in a mixture of EtOAc (200 mL) and NaOH solution (100 mL, 2 N aq.) The layers were separated and the aqueous layer was extracted with EtOAc. The combined organic extracts were filtered and concentrated to give the desired product as a liquid (13.2 g, 85% yield).

Procedure:
In a 100 ml three-necked flask, 5 g of 2,4-bis(benzyloxy)-1-bromobenzene are dissolved in 60 ml of tetrahydrofuran. The mixture is cooled to −70° C. and then 11.4 ml of 2.5M n-butyllithium in hexane are added. The reaction medium is stirred at −70° C. for 1 hour, and then 2.8 g of 1-Boc-azetidine-3-one dissolved in 4 ml of THF are added dropwise. The reaction medium is stirred at −70° C. for 2 hours and then left at ambient temperature overnight. The reaction medium is poured into 40 ml of a 2M solution of hydrochloric acid and then extracted with 100 ml of ethyl acetate. The organic phases are combined, washed with 50 ml of water and then dried over magnesium sulphate and evaporated. The residue is chromatographed on silica gel (AnaLogix SF40-80 g column), elution being carried out with 80/20 heptane/ethyl acetate. 2.2 g of 3-(2,4-bis(benzyloxy)phenyl)-3-hydroxyazetidine-1-carboxylic acid tert-butyl ester are obtained. Yield: 37%.

Procedure:
A glass microwave reaction vessel was charged with 5-(3-(6-chloropyridin-2-yl)-1-tosyl-1H-indol-5-yl)-N-(4-methoxybenzyl)-1,3,4-thiadiazol-2-amine (245 mg, 0.407 mmol) and 4-chlorophenylboronic acid (95 mg, 0.610 mmol) in p-dioxane/H2O (4:1, 4.5 mL) followed by potassium carbonate (168 mg, 1.221 mmol) and Pd(PPh3)4 (23.5 mg, 0.020 mmol). The reaction was stirred and heated in a Initiator microwave reactor (Personal Chemistry, Biotage AB, Inc., Uppsala, Sweden) at 105° C. for 30 min. The mixture was diluted with DCM and washed with H2O and separated. The organic layer was dried, filtered and concentrated. The residue was purified with silica gel chromatography (eluting with 0-20% EtOAc in DCM) to give 5-(3-(6-(4-chlorophenyl)pyridin-2-yl)-1-tosyl-1H-indol-5-yl)-N-(4-methoxybenzyl)-1,3,4-thiadiazol-2-amine (230 mg, 0.339 mmol, 83%) as a light yellow solid.

Procedure:
A solution of the product of Example 224F (118.9 mg, 0.159 mmol) in 1,4-dioxane (3 mL) was treated with a solution of lithium hydroxide monohydrate (13.3 mg, 0.318 mmol) in water (1.5 mL) at ambient temperature, then heated at 70° C. for 45 minutes. The reaction was cooled to room temperature, diluted with ethyl acetate (100 mL) and water (30 mL), adjusted the aqueous pH to 6 with 1N aqueous hydrochloric acid, and separated the layers. The organic phase was washed with water (2×25 mL) and brine (25 mL), dried over anhydrous sodium sulfate, filtered, and concentrated by rotary evaporation in vacuo. Purification of the residue by silica gel chromatography eluting with 5% methanol/methylene chloride afforded the title compound as a yellow solid (51 mg, 61%). 1H NMR (300 MHz, DMSO-d6) δ ppm: 1.34 (d, J=6.99 Hz, 6 H) 3.10-3.34 (m, 1 H) 5.61 (s, 2 H) 6.64 (d, J=8.46 Hz, 2 H) 6.90 (d, J=8.09 Hz, 1 H) 7.15 (d, J=8.46 Hz, 2 H) 7.65 (d, J=8.09 Hz, 1 H) 7.81 (dd, J=7.17, 1.65 Hz, 1 H) 7.97 (s, 1 H) 8.13-8.23 (m, 1 H) 8.32 (d, J=2.57 Hz, 1 H) 8.59 (s, 1 H) 8.76 (d, J=1.47 Hz, 1 H) 8.89 (d, J=8.09 Hz, 1 H) 10.18 (s, 1 H) 10.59 (s, 1 H); MS (ESI+) m/z 526 (M+H)+, (ESI−) m/z 524 (M−H)−.
