With benzotriazol-1-ol; dicyclohexyl-carbodiimide; In benzene; at 20℃; | 0.349 grams of CH3(OCH2CH2)11-NH2 (0.6789 mmoles), 0.044 grams of 1-hydroxybenzyltriazole (0.3328 mmoles), and 0.204 grams of 13-cis-retinoic acid (0.6789 mmoles) was dissolved in 10 mL of benzene. To this solution was added 0.192 g 1,3-dicyclohexylcarbodiimide (0.9318 mmoles) and the reaction mixture was stirred overnight at room temperature. The reaction mixture was filtered and the solvent distilled off using rotary evaporation. The product was dried under vacuum and dissolved in 20 mL dichloromethane. The solution was washed twice with 15 mL of deionized water and the organic phase dried over Na2SO4. The solution was filtered and the solvent was distilled off by rotary evaporation. To the recovered product was added 2 drops of dichloromethane containing 50 ppm butylated hydroxytoluene, and the product was dried under vacuum. Yield 0.541 g. 1H NMR (DMSO): δ 1.01 (s, 2 CH3), 1.68 (s, CH3), 3.5 (br m, PEG), 6.20 (m, 3H). |
