YieldReaction ConditionsOperation in experiment
9.85 g In N,N-dimethyl acetamide; at 140℃; for 8h; General procedure: Example 1 Preparation of Compound Yhhu-0967 (5-methoxy-2,4-diaminoquinazoline) [0029] 2.53 g (79.08 mmol) of methanol was dropped into 5.18 g (86.27 mmol) of 40% sodium hydride suspension in tetrahydrofuran (150 ml) at 0 C. and stirred for 10 min, followed by dropwise addition of 10.0 g (71.89 mmol) of 2,6-difluorobenzonitrile in tetrahydrofuran (100 ml). The reaction mixture as stirred at room temperature for 10 h to complete the reaction. 200 ml of water was added thereto to destroy the excess sodium hydride, and the reaction mixture was extracted with 500 ml of ethyl acetate. The organic layer was dried with anhydrous sodium sulfate and evaporated to dryness. The residue was passed through column chromatography to provide an intermediate. The intermediate and 17.41 g (143.78 mmol) of guanidine carbonate were heated to 140 C. in 300 ml of N,N-dimethylacetamide and stirred for 8 h to complete the reaction. The reaction mixture was evaporated to dryness, then diluted with 200 ml of water and extracted with 400 ml of dichloromethane. The organic layer was dried with anhydrous sodium sulfate and then evaporated to dryness. The residue was passed through column chromatography to proved 9.85 g of compound Yhhu-0967 with a total yield of 72% in the two steps).
