60% With benzotriazol-1-ol; 1-ethyl-(3-(3-dimethylamino)propyl)-carbodiimide hydrochloride; In DMF (N,N-dimethyl-formamide); at 0 - 20℃; (Intermediate Example 89) 3-Amino-1-(1,3-dihydroisoindol-2-yl)-3-methylbutan-1-one 2,3-Dihydro-1H-isoindole (543 mg) and <strong>[625-05-8]3-amino-3-methylbutanoic acid</strong> (700 mg) were dissolved in N,N-dimethylformamide (30 ml). N-(3-Dimethylaminopropyl)-N'-ethylcarbodiimide hydrochloride (876 mg) and hydroxybenzotriazole (698 mg) were added thereto at 0°C, and then the mixture was stirred overnight at room temperature. The reaction mixture was concentrated under reduced pressure, and water and ethyl acetate were added to the residue. The organic phase was separated, and the aqueous phase was adjusted to pH 9 by adding a saturated sodium bicarbonate solution, and then extracted with ethyl acetate. The extract was dried over sodium sulfate and concentrated under reduced pressure to give the title compound (0.60 g, Y.: 60percent) as a brown oily matter. 1H NMR; (CDCl3) delta (ppm): 1.2 (6H, s), 2.4 (2H, s), 4.7-4.8 (4H, m), 7.2-7.3 (4H, m).

YieldReaction ConditionsOperation in experiment
96% With triethylamine; In dichloromethane; at 20℃; for 1h; A solution of 4-formylbenzene sulfonyl chloride (1) (0.50 g, 2.44 mmol) in dichloromethane (5 mL) was treated with isoindoline (0.32 g, 2.68 mmol) and triethylamine (0.41 mL, 2.93 mmol). The resultant mixture was stirred at room temperature for 1 h. A saturated aqueous solution of sodium bicarbonate (10 mL) was added. The product was extracted three times with 10 mL of dichloromethane. The combined organic layers were dried over potassium carbonate, filtered and concentrated in vacuo. The crude material (0.67 g, 96% yield) was used in the next reaction without purification: Crude 1H NMR (400 MHz, CDCl3) delta 10.06 (s, IH), 8.05-8.00 (m, 4H), 7.25-7.20 (m, 2H), 7.20-7.14 (m, 2H), 4.66 (s, 4H); ESI+ MS: m/z (rel intensity) 288.0 (100, [M+H]+).

The cooled reaction solution is evaporated to dryness in a rotary evaporator. The residue is suspended in EA. The undissolved solid is filtered off, rinsed with water and dried, giving 0.56 g of 4-(1,3-dihydroisoindol-2-yl)-6-iodoquinazoline as slightly yellowish solid (yield 93%, content 94%); MS-FAB (M+H+)=373.8; Rf (polar method): 1.73 min.
