Example 251; tert-butyl 5-{[3-(aminocarbonyl)-6,7-diethoxyquinolin-4-yl]amino}-3, 4- dihydroisoquinoline-2 ( H)-carboxylate ; A mixture of 4-chloro-6, 7-diethoxyquinoline-3-carboxamide (178 mg, 0.61 mmole, prepared according to WO 02/092571), tert-butyl 5-amino-3,4-dihydroisoquinoline-2 (1H)- carboxylate (198 mg, 0.80 mmole), acetic acid (7 Ill) in NMP (3 ml) was heated over night at 110 C. The reaction mixture was cooled, partitioned between ethyl acetate and sodium hydrogen carbonate solution. The organic layer was washed with water, dried over sodium sulfate and concentrated in vacuum. The residue was purified by flash chromatography eluting with dichloromethane/methanol (10: 0.5) to give the title compound as a light brown powder (214 mg, 69 %). 1H NMR (399.99 MHz, DMSO-d6) 8 10.63 (1H, s), 8.84 (1H, s), 8.24 (1H, br s), 7.58 (1H, br s), 7.22 (1H, s), 7.06 (1H, t), 6.95 (1H, d), 6.65 (2H, s), 6.61 (2H, d), 4.53 (2H, s), 4.15 (2H, q), 3.59 (2H, t), 3.49 (2H, d), 2.70 (2H, t), 1.39 (9H, s), 1.36 (3H, t), 1.06 (3H, t). APCI-LC/MS m/z: 507.2 [MH+], 201150-73-4
As the paragraph descriping shows that 201150-73-4 is playing an increasingly important role.
