Procedure:
Acetyl chloride (62 ml) was added dropwise to a mixture of ethyl 4-amino-3-nitrobenzoate (142 g), N,N-dimethylaniline (110 ml), and toluene (940 ml) in an ice bath. After stirring the mixture at 50° C. for 3 hours, it was cooled. Water (142 ml) was added thereto to stop the reaction. The toluene layer was separated and the organic layer was washed with dilute hydrochloric acid and successively with water. After the organic layer was concentrated to about 1/3 volume, hexane (284 ml) was added thereto for crystallization. Crystals were collected by filtration and washed with hexane to obtain the desired compound, ethyl 4-(acetylamino)-3-nitrobenzoate (157.7 g).

After the reaction mixture was stirred at room temperature for 10 minutes, it was diluted with ethyl acetate, washed sequentially with aqueous ammonium chloride, saturated aqueous sodium bicarbonate, brine, and lastly dried with anhydrous sodium sulfate. The upper solution was decanted, concentrated, and the solid residue was subject to a gradient column chromatography (from DCM to MeOH-DCM 1:9). The products' fractions were collected, concentrated, and the solid residue was triturated with EtOAc-Hex (6:1) to give N-(6-{[4-({[(3-methylphenyl)amino]carbonyl}amino)phenyl]ethynyl}imidazo[1,2-b]pyridazin-2-yl)cyclopropanecarboxamide as a brown solid upon filtration in amount of 46 mg.

Procedure:
tert-Butyldimethylsilyl chloride (6.63 g) was added portionwise to a solution of imidazole (2.99 g) and 2-(5-(2-hydroxyethyl)thiophen-2-yl)acetic acid (3.9 g) (example 4, step e) in DMF (50 mL) over 20 minutes. The resulting solution was stirred for 1 h. THF (50 mL) was then added and the reaction cooled in an ice bath. A solution of potassium carbonate (4.05 g) in water (50 mL) was then added and the mixture stirred for 20 min. The reaction was partitioned between ethyl acetate and brine. The organic layer was separated and washed twice with brine, dried over sodium sulphate, filtered and the solvent evaporated in vacuo. The residue was dissolved in THF (80 mL) and borane tetrahydrofuran complex (1M solution in THF, 62.8 mL) was added dropwise. The resulting solution was stirred for 2 h and quenched by dropwise addition of methanol (30 mL). The solvents were then evaporated in vacuo. Purification was by silica gel chromatography, eluting with 83:17 isohexane:ethyl acetate to give the subtitled compound as a yellow liquid. Yield 4.6 g.
