实验步骤: A mixture of 5-iodo-pent-1-yne (2.40 g, 12.3 mmol) and morpholine (2.70 g, 30.9 mmol) was heated to 80° C. for 15 min. The mixture was diluted with Et2O and filtered. The solid residue was discarded, and the mother liquor was extracted with 3N HCl. The aqueous layer was made basic with NaOH, and back-extracted into EtOAc. Drying (Na2SO4), and concentration gave the title compound as a pale orange oil. 1H NMR (CDCl3) δ 3.67 (t, 4H), 2.39 (m, 6H), 2.21 (td, 2H), 1.93 (t, 1H), 1.67 (quint., 2H). filtered the mother liquor was extracted with 3N HCl back-extracted into EtOAc Drying (Na2SO4), and concentration

实验步骤: Trifluoro-methanesulfonic acid 1-(3,5-dichloro-pyridin-4-ylmethyl)-6-methoxy-phthalazin-5-yl ester (0.935 g, 2 mmoles), prepared as described in example 73, 4-pent-4-ynyl-morpholine (0.37 g, 2.4 mmoles), diethylamine (9 ml) and dry acetonitrile (6 ml), then bis(triphenylphosphine)PdCl2 (0.014 g, 0.02 mmole) and Cul (0.004 g, 0.02 mmole) were charged in a flask under N2 and the mixture was stirred at room temperature overnight, brought to dryness, the residue taken up in ethyl acetate and washed with water. The organic phase was washed with water, anhydrified and concentrated to give an oil which was flash chromatographed (eluent: CH2Cl2/CH3OH/NH3 95:5:0.5) to give an oil which was dissolved in ethyl acetate and precipitated by adding HCl in ethyl ether. There was yielded 0.09 g of the title compound. m.p.: 129-131° C. (dec.). washed with water The organic phase was washed with water, anhydrified concentrated to give an oil which chromatographed (eluent: CH2Cl2/CH3OH/NH3 95:5:0.5) to give an oil which precipitated by adding HCl in ethyl ether
