N-(1-(5-Fluoropyrimidin-2-yl)vinyl)acetamide (Method 58, 0.10 g, 0.55 mmol) in MeOH (5 ml) under N2 was added (+)-1,2-bis((2S,5S)-2,5-diethylphospholano)benzene (cyclooctadiene)rhodium(I)trifluoromethanesulfonate (0.04 g, 0.0055 mmol). The solution was transferred to a high pressure bomb and charged 150 psi H2. The reaction stirred at room temperature for 4 hours. The solvent was removed and the resulted residue was purified by column chromatography (EtOAc) to give the title compound as a white solid (0.096 g, 95%). 1H NMR (400 MHz) 8.84 (d, J=0.8 Hz, 2H), 8.34 (d, J=7.6 Hz, 1H), 5.00 (m, 1H), 1.84 (s, 3H), 1.37 (d, J=6.8 Hz, 3H). MS: Calcd.: 183. Found: [M+H]+ 184. Enantiomeric excess determined by HPLC (Chiralpak IA; 95:5 CO2/MeOH), >99% ee.
