Chem., 1981, 59, 2673) and 3,4-difluoronitrobenzene (6.5 g, 40.9 mmol) were dissolved in DMF (50 ml) and cooled in an ice-bath. The mixture was stirred and sodium hydride (60percent in oil, 1.6 g, 40 mmol) added over 20 minutes. After allowing the mixture to come to ambient temperature, it was heated to 65° for 1 hour. Solvent was evaporated, the residue triturated with water, and filtered. The crude solide was purified by flash chromatography on silica, eluding with dichloromethane. Relevant fractions were combined to give the title product (3.75 g), mp 117-119°.

General procedure: The example reported for derivatives 22/23 find general application for all the other N-linked heterocycles. Sodium hydride 60percent dispersed in mineral oil was added at 0 °C to a solution of 3-(trifluoromethyl)-1H-pyrazole in dry DMF. The mixture was stirred at this temperature for 15 min, then for an additional 5 min at room temperature. A solution of derivative 45 in dry DMF (2 ml) was then added and the mixture was stirred at 50 °C for 3 h 30 min. After cooling to RT, a saturated NH4Cl solution was added and the mixture was extracted with Et2O (2.x.). The organic phase was washed with brine, dried over Na2SO4 and concentrated in vacuo. The residue was purified by Silica gel flash chromatography (gradient ethyl acetate in cyclohexane from 5 to 40percent) to give the intermediate BOC protected compound 22 and the intermediate BOC protected compound 23.

After addition, the resulting mixture was stirred for 3 h. (7?)- 3-Bromo-N-(4-cyano-3-(trifluoromethyl)phenyl)-2-hydroxy-2-methylpropanamide (8, 0.38 g, 0.00108 mol) was added to above solution, and the resulting reaction mixture was allowed to stir overnight at RT under argon. The reaction was quenched by water, and extracted with ethyl acetate. The organic layer was washed with brine, dried with MgS04, filtered, and concentrated under vacuum. The product was purified by a silica gel column using ethyl acetate and hexanes (1 : 1) as eluent to afford 0.26 g of the titled compound as pinkish solid. (0700) [00319] Compound 1001 was characterized as follows: NMR (400 MHz, DMSO-i delta 10.44 (s, 1H, NH), 8.44 (s, 1H, ArH), 8.24 (d, = 8.8 Hz, 1H, ArH), 8.10 (d, = 8.8 Hz, 1H, ArH), 7.49 (s, 1H, Pyrrole-H), 6.38 (t, J = 2.0 Hz, 1H, Pyrrole-H), 6.41-6.40 (m, 2H, OH and Pyrrole-H), 4.30 (d, = 14.0 Hz, 1H, CH), 4.14 (d, = 14.0 Hz, 1H, CH), 1.34 (s, 3H, CH3); (ESI, Positive): 363.1079[M+H]+.

YieldReaction ConditionsOperation in experiment
After methyl 1H-<strong>[7126-38-7]pyrrole-3-carbonitrile</strong> (2 g, 23.8 mmol) was dissolved in dichloromethane, benzaldehyde (1.2 g, 11.9 mmol) was added thereto, the resulting mixture was stirred for about 15 minutes, one or two drops of trifluoroacetic acid were added thereto, and then the resulting mixture was stirred at room temperature for 12 hours. Thereafter, 2,3-dichloro-5,6-dicyano-p-benzoquinone (2.7 g, 11.9 mmol) was added thereto, and then the resulting mixture was additionally stirred for 15 minutes. N,N-diisopropylethylamine (DIEA) (21.5 g, 166 mmol) was added to the stirred mixture, and then a boron trifluoride-ethyl ether complex (25 g, 178 mmol) was slowly added thereto, and the resulting mixture was additionally stirred for 5 hours. After the stirring was completed, the reaction was terminated with water, the organic layer was extracted using dichloromethane, the extracted material was concentrated, and Intermediate A-1 was synthesized using column chromatography.
