Procedure

The subtitle compound was prepared according to the procedure outlined in example 1 step (iii) using (1R)-1-[(4S)-2,2-dimethyl-1,3-dioxolan-4-yl]ethanol (prepared according to Liebigs Ann. Chem. 1987, 7-14) (0.25 g) and 4,6-Dichloro-2-[(2,3-difluorobenzyl)thio]pyrimidine (the product of example 1 step ii) (0.53 g) in THF (20 mL) and 60% sodium hydride (80 mg). Crude material was purified by column chromatography on silica gel using EtOAc/isohexane (1:3) as eluent to give the subtitle compound as a clear, colourless oil. Yield: 0.37 g.
