YieldReaction ConditionsOperation in experiment
10.9% With potassium carbonate; In 1-methyl-pyrrolidin-2-one; at 80℃; for 2h; Preparation of Compound 77 Compound 75 was prepared according to J. Heterocycl. Chem., 2003, 487. Compound 75 (10 g, 71.4 mmol), compound 76 (20 g, 89.2 mmol) and K2CO3 (12.328 g, 89.2 mmol) were dissolved in NMP (60 ml), and the mixture was heated to 80° C. for 2 h. The reaction mixture was allowed to cool and diluted with a mixture of ethyl acetate: water=3:1 (500 ml). The water layer was washed with EtOAc (3.x.100 ml), and the organic layers were dried over Na2SO4, and concentrated in vacuo. The residue was purified on silica gel (PE:EA=100:1 to 20:1) to give compound 77 as yellow oil (2.2 g, 10.9percent). 1H NMR (400 MHz, CDCl3): 0.860 (q, 6H, J=4 Hz), 0.978 (m, 1H), 1.213 (m, 1H), 1.372 (t, 3H, J=7.2 Hz), 1.555 (m, 2H), 2.329 (m, 2H), 3.709 (s, 3H), 4.334 (q, 2H, J=7.2 Hz), 5.907 (q, 1H, J=5.2 Hz), 6.896 (d, 1H, J=2 Hz), 7.587 (d, 1H, J=2 Hz). MS-ESI: m/z=283.1 [M+1]+.
