Procedure:
The title compound was prepared by the same procedure as Example 3 except that 2-amino-4H-indeno[1,2-b]thiophene-3-carboxylic acid amide was replaced with 2-amino-4,5-dihydro-naphtho[1,2-b]thiophene-3-carboxylic acid amide to give the above title compound as brown solid. ESMS m/z: 287 [M+H]+.

Procedure:
Phenol was acetylated with a 1.5 times molar excess of acetyl chloride at room temperature, the excess acetyl chloride being removed by evaporation under reduced pressure. A very high yield of phenyl acetate was produced. To this reaction product a 2.4 times molar excess of acetic anhydride was added with stirring, followed by a 1.5 times molar excess of sulphuric acid added dropwise at 50° C. over 30 minutes. After stirring for a further 60 minutes, the mixture was neutralised using a 1.5 time molar excess of sodium acetate in glacial acetic acid solution. Trituration of the reaction mixture with ether followed by filtration resulted in a dry yellow solid. This was recrystallised from methanol and washed with sodium carbonate solution. A 99% conversion to sodium sulphonatophenyl acetate was achieved.

Procedure:
One equivalent each of hydroxyacetic acid (10.0 g), dicyclohexylcarbodiimide, (L)-alanine ethyl ester hydrochloride and imidazole was stirred in 500 mL acetonitrile. The reaction mixture, initially at 0° C. was allowed to warm to room temperature overnight and then heated at 65° C. for 2 hours. After the addition of an equal volume of toluene, the reaction mixture was filtered and the solvent removed by rotovaping from the filtrate to give crude product. An aliquot of the crude product was chromatographed on silica gel to give N-(hydroxyacetyl)alanine ethyl ester (61% yield). 1H NMR (300 MHz, DMSO-d6 /TMS): δ1.19 (t , 3H, J=7.1 Hz), δ1.31 (d, 3H, J=7.2 Hz), δ3.83 (s, 2H), δ4.09 (d×q, 2H, J=1.2 and 7.1 Hz, irradiation in the methyl region eliminates the smaller coupling constant), δ4.32 (d×q, 1H, J=7.3 and 7.3), and δ 8.31 (br d, 1H, J=7.2 Hz). 13C NMR (75 MHz, CDCl3 /TMS): 13.59, 17.54, 47.31, 61.02, 61.48, and 172.17.

Procedure:
Tetrabutylammonium fluoride (50 mg, 1M solution in tetrahydrofuran) was added to an ice-cooled solution of (trifluoromethyl)trimethylsilane (2.1 g, 15 mmol) and tert-butyl 4-oxo-1-piperidinecarboxylate (2 g, 10 mmol) in tetrahydrofuran (20 ml), and the reaction stirred at room temperature for 18 hours. The mixture was concentrated under reduced pressure, the residue suspended in ethyl acetate, hydrochloric acid (20 ml, 1N) was added, the mixture stirred for an hour, and then neutralised using sodium bicarbonate. The solution was washed with water, then brine, dried (MgSO4) and evaporated under reduced pressure to give a gum. This was purified by column chromatography on silica gel using an elution gradient of dichloromethane:methanol (100:0 to 98:2) to afford the title compound, 1.94 g.

Procedure:
5-amino-3-((3-chlorophenyl)amino)-1H-pyrazole-4-carboxamide (100 mg) was then suspended in EtOH (4 mL) and 4-(pyrimidin-2-yloxy)benzaldehyde (80 mg, 1 eq.) and piperidine (1 drop) were added. Stirred at reflux until intermediate was absent (HPLC). After reaction was complete (18 hrs) it was brought to room temperature and filtered to obtain product as a yellow powder. Powder was washed with EtOH. Product was allowed to dry under vacuum for 1 hr (104 mg, 60% yield). Resulting imine (104 mg) was suspended in 5 mL MeOH and sodium borohydride (10 eq, 100 mg) was added. HPLC confirmed reaction was complete (absence of imine). After completion (1 hr), precipitate was filtered to obtain D32 as a light yellow powder. Product was washed with deionized water to remove excess sodium borohydride. Product was allowed to dry under vacuum for 18 hrs. 31 mg (30% yield) of final product was obtained.
