Reaction Steps

tert-Butyl 4-(2-{2-cyclopentyl-5-[(5,7-dimethyl[1,2,4]triazolo[1,5-a]pyrimidin-2-yl)methyl]-4-hydroxy-6-oxo-3,6-dihydro-2H-pyran-2-yl}ethyl)-2-ethylbenzylcarbamate (35 mg, 0.06 mmol, example A(126)) was dissolved in dichloromethane (1 mL) and 4N HCl in dioxane (0.5 mL) and stirred at room temperature 2 h. The solution was concentrated to give an off-white solid (30 mg, 96%). 1H NMR (300 MHz, CDCl3): δ ppm 1.14 (t, J=7.54 Hz, 3H) 1.37-1.49 (m, 1H) 1.52-1.66 (m, 6H) 1.67-1.77 (m, 2H) 2.05-2.16 (m, 2H) 2.58 (s, 4H) 2.60-2.70 (m, 6H) 2.74-2.80 (m, 1H) 3.80 (d, J=14.51 Hz, 2H) 4.02 (q, J=5.78 Hz, 2H) 7.07 (s, 1H) 7.13 (s, 1H) 7.16-7.21 (m, 1H) 7.32 (d, J=7.72 Hz, 1H) 8.15 (s, 3H). MS (ESI): 504 (M+H)+.
