With triethylamine; In dichloromethane; at 5 - 20℃; for 20h; | The solution of 3-dimethylaminophenyl isocyanate in 0.14 N tetrahydrofuran can be prepared in the following way: 1.46 g (7 mmol) of N1,N1-dimethylbenzene-1,3-diamine dihydrochloride, followed by 9.9 cm3 (71.64 mmol) of triethylamine, are added, at a temperature in the region of 5 C., under an argon atmosphere, to 2.82 g (9.5 mmol) of triphosgene in solution in 150 cm3 of dichloromethane. After stirring for 20 hours at a temperature in the region of 20 C., the reaction mixture is concentrated to dryness under reduced pressure (2.7 kPa), to give a residue which is triturated in 50 cm3 of tetrahydrofuran. After filtration, a solution of 3-dimethylaminophenyl isocyanate in approximately 0.14 N tetrahydrofuran is obtained, which solution is used directly in the subsequent step. |

With sodium hydrogencarbonate; In water; ethyl acetate; | Commercially available N,N-dimethyl-1,3-phenylene diamine dihydrochloride salt (12 g) was neutralized with solid NaHCO3 (partitioned between H2O and EtOAc). After neutralization, the phases were separated and the organic phase dried and concentrated to give a brownish oil (7.8 g, 57.3 mmol) which was used as is in the next step. Dimethyl acetylene dicarboxylate 15 (7.044 mL, 57.3 mmol) was dissolved in MeOH and treated with the neutralized aniline 16 (portionwise) in MeOH at 0 C. Considerable heat was generated (exothermic reaction). The mixture (brown) was heated at 65 C. for 2 hours. The brown solution was concentrated to dryness, extracted into EtOAc and washed with sat. NaHCO3 (aq), followed by brine, dried (MgSO4), filtered, and concentrated. The crude mixture was purified by flash chromatography using a 10% EtOAc/hexane solvent to afford 12 g of compound 17.

77% | With N-ethyl-N,N-diisopropylamine; In 1-methyl-pyrrolidin-2-one; at 160℃; for 18h; | Example 149; The mixed halo-products (3:1 Cl:Br) from Preparative Example 102 (3.67 g, 15.0 mmol), were combined with N,N-dimethyl-m-phenylenediamine.2HCl (4.71 g, 22.5 mmol), i-Pr2NEt (15.7 mL, 90.2 mmol), and NMP solvent (75 mL). The reaction was heated in an oil bath at 160 C. for 18 hours. The reaction was cooled and concentrated under vacuum. The crude material was purified by column chromatography; 2 columns using a gradient of 20% EtOAc/Hexanes increasing to 50% EtOAc/Hexanes. The product 149 was isolated in 95% purity as determined by 1H NMR (400 MHz DMSO-d6,) 9.36 (s, 1H), 7.77 (s, 1H), 7.74 (d, J=4.4 Hz, 1H), 7.54 (d, J=4.8 Hz, 1H), 7.47 (m, 1H), 7.42 (t, J=2.0 Hz), 7.09 (t, J=8.0 Hz, 1H), 6.40 (dd, J=8.0 Hz, 2.0 Hz, 1H), 2.87 (s, 6H). Product was isolated in 77% yield, 3.83 g. |
