Reaction Steps

A mixture of (1S,2S,3R,5S)-3-amino-5-(2-hydroxyethoxy)cyclopentane-1,2-diol (OLA; 1.06 g, 6 mmol), 4,6-dichloro-2-(propylthio)pyrimidin-5-amine (CLINA; 1.43 g, 6 mmol), triethylamine (1.09 g, 7.8 mmol) and polyethyleneglycol PEG400 (2 mL) was stirred for 48 h at 75° C. The reaction mixture was diluted with ethyl acetate (50 mL), washed with water (25 mL) and evaporated under reduced pressure to give a resinous material which solidified upon trituration in n-hexane (25 mL). After filtration there was obtained OLACINA as a grey powder (2.0 g, 88% yield): 13C NMR (DMSO-d6, 125 MHz) δ13.3, 22.8, 32.2, 34.7, 54.8, 60.4, 69.8, 72.4, 75.2, 82.4, 119.9, 137.5, 152.5, 155.1.
