Reaction Steps

To a solution of 2,4-dichloro-5-nitropyrimidine (1.5 g, 7.73 mmol) in EtOH (25 ml) at 0° C. was added triethylamine (1.6 ml, 11.6 mmol) and a solution of (2R)-2amino-2-(4-fluorophenyl)ethanol (prepared according to a procedure in J. Med. Chem. 1999, 42, 4981-5001, 1.2 g, 7.73 mmol). The reaction mixture was stirred at 0° C. for 3 hours. The solvent was removed and the residue was dissolved in EtOAc and was washed with water. The organic layer was concentrated. Flash chromatography on silica gel (20-50% EtOAc in hexanes) gave the title compound as a solid (703 mg, 29%). NMR (CDCl3) 4.00 (m, 2H), 5.50 (m, 1H), 7.07 (m, 2H), 7.38 (m, 2H), 9.04 (s, 1H), 9.10 (br s, 1H).
