실험 절차

To a stirred solution mixture of 5-benzyloxy-6-hydroxy-2-(1-phenyl-cyclopentylmethyl)-pyrimidine-4-carboxylic acid (283) (230 mg, 0.57 mmol) and [2-(tert-butyl-dimethylsilanyloxy)-ethyl]-(2,2-dimethyl-propyl)-amine (8h) (167 mg, 0.68 mmol) in dimethylformamide (2.2 mL) were added N,N-diisopropylethylamine (0.3 mL, 1.70 mmol) and HATU (324 mg, 0.85 mmol). The reaction was stirred at room temperature for 20 h. Water (75 mL) was added and the mixture was extracted with ethyl acetate (3×20 mL). The combined organic part was washed with water (3×50 mL) and brine (2×30 mL) and dried and concentrated. The crude product was purified by Combi-Flash column (eluted at 20-30% ethyl acetate in hexane) to get 5-benzyloxy-6-hydroxy-2-(1-phenyl-cyclopentylmethyl)-pyrimidine-4-carboxylic acid [2-(tert-butyl-dimethylsilanyloxy)-ethyl]-(2,2-dimethyl-propyl)-amide (300) (310 mg, 86.27%) as an off-white sticky solid.
