Procedure: To a round bottomed flask containing 7-benzyl-2-chloro-4-phenyl-5,6,7,8-tetrahydropyrido[3,4-d]pyrimidine (73 mg, 0.22 mmol) was added commercially available 4-amino-N-(2,6-dimethylphenyl)benzamide (56 mg, 0.23 mmol), diacetoxypalladium (II), (12 mg, 0.05 mmol) di-tert-butyl(phenyl)phosphine (39 mg, 0.13 mmol), cesium carbonate (125 mg, 0.38 mmol), and toluene (5 mL). The reaction mixture was heated to 100° C. for 14 h, then cooled to rt and diluted with ethyl acetate. The organic layer was washed with saturated sodium bicarbonate, dried over sodium sulfate, filtered, and concentrated on a rotary evaporator. The material was purified by flash column chromatography to afford N-(2,6-dimethylphenyl)-4-{[4-phenyl-7-(phenylmethyl)-5,6,7,8-tetrahydropyrido[3,4-d]pyrimidin-2-yl]amino}benzamide (60 mg, 50%) as an off white solid. 1H NMR (400 MHz, DMSO-d6): δ 9.95 (s, 1H), 9.53 (s, 1H), 7.93 (m, 4H), 7.61 (m, 2H), 7.50 (m, 3H), 7.29 (m, 5H), 7.11 (m, 3H), 3.64 (m, 2H), 3.56 (m, 2H), 2.90 (m, 2H), 2.81 (m, 2H), 2.17 (s, 6H). MS (EI) for C35H33N5O: 540.3 (MH+). cooled to rt The organic layer was washed with saturated sodium bicarbonate dried over sodium sulfate filtered concentrated on a rotary evaporator The material was purified by flash column chromatography

Conditions: temp:4.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a solution of 2.0 g of 4-amino-N-(2,6-dimethylphenyl)benzamide in dimethylformamide were added 1 ml of pyridine followed by 710 μl of acetyl chloride. The reaction was stirrred at room temperature for 2 hours, diluted with water, and chilled to approximately 4° C. The title product was recovered by filtration in 85% yield, m.p. 293°-295° C. The title product was recovered by filtration in 85% yield, m.p. 293°-295° C.

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A solution of 5.0 g of 4-nitro-N-(2,6-dimethylphenyl) benzamide in 250 ml of ethanol was added to a Paar hydrogenation bottle along with 250 mg of 5% palladium on carbon. The mixture was subjected to low pressure hydrogenation (45 psi) for three hours. The mixture was filtered through celite and the filtrate was evaporated in vacuo. The resulting residue was purified by (crystallization from benzene-petroleum ether) [column chromatography over silica gel using a step-wise solvent gradient of petroleum ether and diethyl ether] to provide 2.2 g of the desired title product, m.p. 212°-215° C. The mixture was filtered through celite the filtrate was evaporated in vacuo The resulting residue was purified by (crystallization from benzene-petroleum ether) [column chromatography over silica gel using a step-wise solvent gradient of petroleum ether and diethyl ether]
