YieldReaction ConditionsOperation in experiment
With triethylamine; In tetrahydrofuran; dichloromethane; at 0℃; for 1.5h; 2-ethoxyl benzoic acid (10.0g, 60.2mmol) was added into thionyl chloride (20ml), and the mixture was refluxed with agitation for 40 minutes, and the excess amount of thionyl chloride was evaporated under reduced pressure. The residual was dissolved into dichloromethane (150ml). Within 30 minutes and being stirred on ice bath, the afore-obtained solution of 2-ethoxyl benzoyl chloride was dropped into the compound (1a) (7.0g, 56.8mmol) dissolved in tetrahydrofuran (80ml) and triethylamine (8.5ml, 61.0mmol). After completion, the mixture was stirred for 1 hour at 0C . After being washed with water and filtrated with diatomaceous earth, the reaction solution was mixed with 20g of silica gel and evaporated to dryness. The resulting residual was eluted with dichloromethane by using silica gel(80g) column to obtain 7.5g of solid product (3a) with the yield of 48%. Furthermore, the sample for analysis was prepared by column chromatography (developing agent: dichloromethane: n-hexane=1:2) and recrystallization (dichloromethane: n-hexane=1:5). mp 183~184C (sublimation 162C); IR (cm-1) : 3326, 3309, 2981, 2938, 2915, 2854, 2208, 1647, 1593, 1471, 1309, 1302, 1232, 1039, 923, 727, 655, 648; 1H NMR (CDCl3) : delta 1.70 (t, J=7.0Hz, 3H), 2.15 (s, 3H), 4.32 (q, J=7.0Hz, 2H), 6.24 (s, 1H), 7.04 (d, 1H), 7.10 (m, 1H), 7.51 (dd, 1H), 8.20 (dd, J=7.9 and 1.8Hz, 1H), 10.69 (brs, 1H), 10.80 (s, 1H); 13CNMR (CDCl3) : delta (CH3) 10.6, 15.0; (CH2) 65.7; (CH) 110.3, 112.3, 121.4 132.1, 134.2; (C) 78.7, 115.6, 119.2, 119.4, 136.7, 157.0, 163.2; MS (ES+) : m/z 287 (M+NH4) .
