実験手順

A mixture of (1R,2S,3R,5R)-3-amino-5-(hydroxymethyl)cyclopentane-1,2-diol hydrochloride (16.9 g, 45.1 mmol) and 4,6-dichloropyrimidin-5-amine (5.7 g, 35 mmol) in ethanol (45 mL) was evenly distributed amongst three tubes and subjected to microwave conditions (CEM apparatus, 300 W max, 150° C. max, 250 psi max, 3 min ramp, 30 min hold) to afford brown solutions; HPLC/LC MS indicated conversion to the desired product. The three reaction mixtures were combined and concentrated in vacuo to afford the crude title compound as a dark brown oil, which was concentrated from toluene (2×30 mL) and carried on without purification: MS (ESI+) for C10H15ClN4O3 m/z 275.0 (M+H)+; MS (ESI−) for C10H15ClN4O3 m/z 273.0 (M−H)−.
