Procedure

A mixture of N-[(1R,3S,4S)-3-{[tert-butyl(dimethyl)silyl]oxy}-4-({[tert-butyl(dimethyl)silyl]oxy}methyl)cyclopentyl]-6-chloropyrimidin-4-amine (0.114 g, 2.42 mmol), (1R,2S)-2-methoxyindan-1-amine (0.170 g, 1.04 mmol) and Na2CO3 (0.10 g, 0.97 mmol) was heated to 180° C. for 2 h in a sealed tube using an oil bath. The reaction was cooled and filtered. The filtrate was concentrated in vacuo. The residue was purified by flash chromatography (50 to 60% EtOAc/hexanes) to afford the title compound as a beige foam (0.066 g, 46%). LC/MS: Rt=2.20 min, ES+ 599 (Formic Acid).
