Procedure

Prepared as described in example 24 using 2-chloro-4-(trifluoromethyl)pyrimidine in place of 4-chloro-6-(trifluoromethyl)pyrimidine and modifying step 9 as follows. The HCl salt of 1,5-anhydro-2,3-dideoxy-3-{[(1R,3S)-3-{[(1S,4S)-2,5-diazabicyclo[2.2.1]hept-2-yl]carbonyl}-3-(2,2-difluoroethyl)cyclopentyl]amino}-4-O-methyl-D-erythro-pentitol (175 mg, 0.41 mmol) was placed in flask with 1,4-dioxane (3 ml). Triethylamine (0.2 ml, 1.43 mmol) was added as well as 2-chloro-4-(trifluoromethyl)pyrimidine (237 mg, 1.30 mmol). DMSO (0.3 ml) was added for solubility and the reaction was heated to 100° C. for 14.5 hours. The reaction was cooled to room temperature and partitioned between ethyl acetate and water. The aqueous layer was extracted with ethyl acetate and the combined organics were washed with brine, dried over MgSO4, concentrated under reduced pressure and purified with the Biotage (0-100% methanol/ethyl acetate 15 column volumes) to give 1,5-anhydro-2,3-dideoxy-3-{[(1R,3S)-3-(2,2-difluoroethyl)-3-({(1S,4S)-5-[4-(trifluoromethyl)pyrimidin-2-yl]-2,5-diazabicyclo[2.2.1]hept-2-yl}carbonyl)cyclopentyl]amino}-4-O-methyl-D-erythro-pentitol as a brown foam (126 mg, 58%).
