Reaction Steps
To 10 mL of dioxane was added 0.159 g of 4'-[[[2-[(3-methylbutyl)amino]-4-quinazolinyl]amino]methyl][1,1'-biphenyl]-2-carboxylic acid methyl ester and 2 mL of 0.5N aqueous sodium hydroxide. The resulting solution was stirred at room temperature for 72 hours. All solvents were moved and the residue was neutralized with 0.1N hydrochloric acid. The resulting precipitate was collected, washed with water and dried. (0.14 g, 93%) (M.P.=195°-205° C., decomp): 1H NMR (DMSO-d6, 300 MHz) δ8.43 (bs, 1H), 8.03 (m, 1H), 7.70 (m, 1H), 7.59 (m, 1H), 7.45 (m, 5H), 7.21 (m, 3H), 7.01 (m, 1H), 6.50 (bs, 1H), 4.78 (d, 2H), 3.50 (m, 2H), 1.60 (m, 1H), 1.40 (m, 2H), 0.85 (d, 6H); negative FAB MS m/e 439 (M--H). Anal. Calcd for C27H28N4O2.1/2HCl: C, 70.69; H, 6.26; N, 12.53. Found: C, 70.77; H, 6.20; N, 12.53.
