Procedure

5-Benzyloxycarbonylamino-2-(4-methylimidazol-1-yl)fluorobenzene (54 g, 0.166 M) was dissolved in a mixture of dry tetrahydrofuran (600 ml) and 1,3-dimethyl-2,4,5,6-tetrahydro-2(1H)-pyrimidinone (100 ml) under nitrogen, cooled to −70°, and treated with a solution of n-butyllithium (1.6 M in isohexane, 114 ml), over 30 minutes. After stirring for 30 minutes at 25–70°, a solution of (R)-glycidylbutyrate (26.35 g, 0.183 M) in dry tetrahydrofuran (50 ml) was added over 15 minutes. Stirring was continued for 16 hours allowing the temperature to rise to ambient. The mixture was treated with aqueous sodium bicarbonate (5%, 500 ml) and ethyl acetate (800 ml), and undissolved solid was removed and washed well with diethyl ether to give title product (16.3 g).
