Versuchsvorschrift

To a stirred solution mixture of 5-benzyloxy-6-hydroxy-2-(1-phenyl-cyclopentylmethyl)-pyrimidine-4-carboxylic acid (283) (250 mg, 0.62 mmol) and [2-(tert-butyl-dimethylsilanyloxy)-ethyl]-cyclopropylmethyl-amine (8i) (170 mg, 0.74 mmol) in dimethylformamide (3 mL) were added N,N-diisopropylethylamine (0.3 mL, 1.85 mmol) and HATU (352 mg, 0.93 mmol). The reaction mixture 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 5-benzyloxy-6-hydroxy-2-(1-phenyl-cyclopentylmethyl)-pyrimidine-4-carboxylic acid [2-(tert-butyl-dimethylsilanyloxy)-ethyl]-cyclopropylmethyl-amide (304) (380 mg, 99.82%) as a light yellow sticky solid.
