43% With N-ethyl-N,N-diisopropylamine; In ISOPROPYLAMIDE; at 80℃; for 0.5h; Example 4 1-(4-Amino-8-fluoro-quinazolin-7-yl)-3,6,6-trimethyl-1,5,6,7-tetrahydro-indol-4-one (Compound 4); <strong>[143879-80-5]2,3,4-Trifluoro-benzonitrile</strong> (3.00 g, 19.1 mmol) is mixed with dimethylacetamide (30 mL). Formamidine acetate (1.99 g, 19.1 mmol) and diisopropylethyl amine (10 mL, 57.3 mmol) are added, and the resulting reaction mixture is slowly heated. Upon heating, the starting heterogeneous mixture slowly turns into a homogeneous solution. At 80° C., precipitates start to form. The reaction mixture proceeds at 80° C. for 30 minutes before it is cooled and filtered. The collected solid is further washed with DCM to afford 1.50 g of 7,8-Difluoro-quinazolin-4-ylamine (43percent yield) as white solid. LC/MS found m/z=182 [M+H]+.

With N-ethyl-N,N-diisopropylamine; In dimethyl sulfoxide; at 20℃; for 68h; Scheme 21[0368] To <strong>[143879-80-5]2,3,4-<strong>[143879-80-5]trifluorobenzonitrile</strong></strong> (265 mg, 1.68 mmol) in a flask, a solution of D- leucine amide hydrochloride (282 mg, 1.68 mmol) and DIEA (0.880 mL, 5.06 mmol) in DMSO (5 mL) was added. After being stirred at room temperature for 68 h, water and EtOAc were added. The organic phase was separated, washed with water, dried over Na2S04, concentrated in vacuo. The residue was purified by a silica gel column, eluted with 0-70percent EtOAc in hexane to give (R)-2-(4-cyano-2,3-difluorophenylamino)-4-methylpentanamide (113 mg).

YieldReaction ConditionsOperation in experiment
11.4% With potassium phosphate; In 1-methyl-pyrrolidin-2-one; at 115℃; for 18h;Inert atmosphere; 2.5 g (15.9 mmol) <strong>[143879-80-5]2,3,4-<strong>[143879-80-5]trifluorobenzonitrile</strong></strong>, 10.9 g (52.5 mmol) 6H-benzimidazolo[1 ,2- a]benzimidazole and 27.0 g (0.127 mol) potassium phosphate tribasic in 50 ml NMP (N-Methyl- 2-pyrrolidon) are stirred at 1 15 °C under nitrogen for 18 h. The reaction mixture is filtered hot and the organic phase is poured on water. The product is filtered of. Column chromatography on silica gel with chloroform gives 1 .3 g (1 1.4 percent) of the product. 1H NMR (300 MHz, DMSO-D6): rotamers: delta 8.55-8.82 (m, 2H); 6.41 -8.07 (m, 24H) MS (APCI(pos), m/z): 719 (M+1).
