Procedure
To a neat mixture of (1S,2R,4R)-4-amino-2-(hydroxymethyl)cyclopentanol (3.00 g, 22.9 mmol) and 4,6-dichloropyrimidine (3.70 g, 24.8 mmol) was added isopropyl alcohol (30.0 mL) and Et3N (8.00 mL, 57.4 mmol) and the resulting mixture was heated to 90° C. for 1 h. The mixture was then cooled to 23° C., filtered and concentrated in vacuo. The residue was purified via silica gel chromatography eluting with a gradient of 5 to 7% MeOH in DCM, and the compound was recrystallized from EtOAc to afford the title compound as a white solid (3.30 g, 59%). LC/MS: Rt=0.84 min, ES+ 244 (AA standard).
