Step II: 6-Amino-5-methyl-pyridine-3-carboxylic acid To a stirred suspension of 6-amino-5-methyl-pyridine-3-carbonitrile (6.0 g, 45.0 mmol) in water (40 mL) was added sodium hydroxide (5.4 g, 135.2 mmol) and refluxed for 4 h. Reaction mixture was cooled to room temperature and filtered through Buchner funnel. Filtrate was neutralized with 4N HCl. Solid formed was filtered through Buchner funnel and dried under high vacuum to furnish 6.0 g (88%) of titled intermediate as a white solid. 1H NMR (400 MHz, CDCl3): delta 2.05 (s, 3H), 6.53 (s, 2H), 7.66 (s, 1H), 8.37 (d, J=2.0 Hz, 1H), 12.29 (brs, 1H).

EXAMPLE 17 (E)-6-((4-Amino-8-(4-(2-cyanovinyl)-2,6-dimethylphenyl)quinazolin-2-yl)amino)-5- methylnicotinonitrile- Compound 17 Synthesis of (£)-6-((4-amino-8-(4-(2-cyanovinyl)-2,6-dimethylphenyl)quinazolin-2- yl)amino)-5-methylnicotinonitrile (compound 17) [0281] Compound 2a (20 mg, 0.06 mmol), 6-amino-5-methylnicotinonitrile (24 mg, 0.18 mmol, Ark Pharm Inc, AK-25043), N,N-diisopropylethylamine (622 mg, 0.48 mmol), (9,9- dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine) (4 mg, 0.006 mmol) and palladium (II) acetate (1 mg, 0.006 mmol) were combined under argon in N-methyl-2-pyrrolidone (1 mL). The reaction was heated at 120C in a sealed vessel for 4 hours. The reaction mixture was cooled down to room temperature and diluted with water and ethyl acetate. The organic layer was separated and washed twice with brine, dried over magnesium sulfate and this solution was filtered through a 2 cm layer of silica gel which was washed with additional ethyl acetate. Combined organics were concentrated down under reduced pressure. The crude residue was treated with diethyl ether in the sonic bath for 5 minutes. The solid compound was filtered off and washed twice with diethyl ether and once with hexane to afford the title compound 17. *H NMR (400 MHz, DMSO-Patent; GILEAD SCIENCES, INC.; INSTITUTE OF ORGANIC CHEMISTRY AND BIOCHEMISTRY OF THE AS CR, V.V.I.; JANSA, Petr; SIMON, Tetr; LANSDON, Eric; HU, Yunfeng, Eric; BASZCZYNSKI, Ondrejj; DEJMEK, Milan; MACKMAN, Richard, L.; (185 pag.)WO2016/105564; (2016); A1;,
