Procedure:
Methyl 5-chloro-2-pyridazinecarboxylate (CAS#33332-25-1) is hydrolyzed to the corresponding carboxylic acid, 5-chloropyrazine-2-carboxylic acid. This acid is then converted to the corresponding acid chloride, 5-chloropyrazine-2-carbonyl chloride, by treatment with either thionyl chloride or oxalyl chloride. This acid chloride is then treated with a 2 M solution of methylamine in tetrahydrofuran to provide 5-chloro-N-methylpyrazine-2-carboxamide. The procedure of Example 48 is then repeated, substituting 5-chloro-N-methylpyrazine-2-carboxamide in place of 6-chloro-N-methyl-3-pyridinecarboxamide to give (R)—N-methyl-5-(2-(3-(piperidin-1-yl)pyrrolidin-1-yl)benzo[d]thiazol-6-yloxy)pyrazine-2-carboxamide.

Procedure:
4-Amino-3-chlorobenzonitrile (1.50 g (9.83 mmol)) was dissolved in 5.0 ml of pyridine. To this, p-toluenesulfonyl chloride (1.90 g (9.97 mmol)) was added under cooling with ice and with stirring. After stirring for 18 hours at room temperature, water (100 ml) was added to the reaction mixture to bring about separation of crystals. The crystals were filtered, washed with water and then dissolved in an aqueous solution of sodium hydroxide. The resulting solution was washed with diethyl ether, and the water layer was made acidic again with hydrochloric acid and extracted with chloroform. The extract was dried over anhydrous magnesium sulfate and concentrated under reduced pressure to give 1.65 g (55%) of 2′-chloro-4′-cyano-p-toluenesulfonanilide as white crystals.

To 3-bromo-7-{[2-chloro-3-(trifluoromethyl)phenyl]carbonyl}-5,6,7,8-tetrahydro[1,2,4]triazolo[4,3-a]pyrazine (0.150 g, 0.366 mmol, e.g. see Example 1 for methods of preparation) in 1,2-dimethoxyethane (DME) (3 mL) was added aqueous sodium carbonate solution (1.9 mL, 1 M) followed by phenylboronic acid (0.067 g, 0.549 mmol, commercially available e.g. from Sigma-Aldrich or Strem Chemicals) and dichlorobis(triphenylphosphine)palladium(II) (0.013 g, 0.018 mmol). The reaction mixture was heated at reflux for 7 hours. The mixture was diluted with water (10 mL) and extracted with ethyl acetate (twice). The combined organic fractions were dried, filtered and evaporated. An attempt to purify the crude material on silica gel chromatography using methanol in Dichloromethane (0-20%) as eluent was unsuccessful. The residue was then purified using mass-directed automated (preparative) HPLC (MDAP) to give 7-{[2-chloro-3-(trifluoromethyl)phenyl]carbonyl}-3-phenyl-5,6,7,8-tetrahydro[1,2,4]triazolo[4,3-a]pyrazine (0.076 g) as a white solid.

Procedure:
A solution of 110 mg (0.2 mmol) of crude tert-butyl (3RS,4RS)-4-[4-(2-methylsulphonyloxy-ethoxy)-phenyl]-3-(naphthalen-2-ylmethoxy)-piperidine-1-carboxylate in 5 ml of dimethylformamide was treated with 70 mg (1.0 mmol) of 1,2,4-triazole sodium salt and the reaction mixture was heated to 100° C. for 6 hours. Subsequently, the mixture was cooled to room temperature and the dimethylformamide was distilled off in an oil pump vacuum. The residue was taken up in 10 ml of methylene chloride, washed with 2 ml of water, the organic phase was dried over sodium sulphate and evaporated under reduced pressure. The residue was chromatographed on silica gel using a 95:5:0.1 mixture of methylene chloride, methanol and ammonia as the eluent. There were obtained 90 mg (85% of theory) of tert-butyl (3RS,4RS)-3-naphthalen-2-ylmethoxy-4-[4-(2-[1,2,4]triazol-1-yl-ethoxy)-phenyl]-piperidine-1-carboxylate as a colourless oil; MS: 529 (M+H)+.

Procedure:
To a solution of 3-(bromomethyl)-benzaldehyde (0.467 g, 2.44 mmol) in dichloroethane (20 mL) was added cycloleucine cyclopentyl ester (0.802 g, 4.06 mmol) and sodium triacetoxyborohydride (1.18 g, 5.56 mmol). The mixture was stirred at room temperature for 3 hours, then poured into ethyl acetate (200 mL) and washed with saturated ammonium chloride solution (3 times 50 mL). The organic fraction was dried (MgSO4), concentrated and purified by flash column chromatography (SiO2, 7:3 heptane:ethyl acetate) to yield the desired product (0.568 g, 61% yield).
