Reaction Steps

A mixture of N-[(1R,3S,4S)-3-{[tert-butyl(dimethyl)silyl]oxy}-4-({[tert-butyl(dimethyl)silyl]oxy}methyl)cyclopentyl]-6-chloro-5-fluoropyrimidin-4-amine (205 mg, 0.38 mmol), (1S)-3,3-dimethylindan-1-amine (243 mg, 1.51 mmol), and sodium carbonate (160 mg, 1.51 mmol) was stirred at 180° C. for 3 h in an oil bath. The reaction mixture was diluted with DCM and the suspension was filtered. The filtrate was concentrated under vacuum and the residue was purified by flash chromatography (5 to 10% ethyl acetate/hexanes) to afford the title compound (213 mg, 70%) as a colorless amorphous solid.
