Procedure
The title compound was prepared substantially following the procedures as set forth in Method B, Example 12, and employing ((R)-3-amino-2-hydroxy-propyl)-cyclohexylmethyl-phosphinic acid benzyl ester hydrochloride and N-Cbz-Trp-Val-OH as the staring materials, which yielded the title compound as a white powder. 1H NMR (CD3OD, 300 MHz): δ 7.65-7.62 (d, 1H), 7.38-7.35 (d, 1H), 7.17-7.01 (m, 3H), 4.26-4.20 (m, 1H), 4.17-4.14 (d, 1H), 4.05 (m, 1H), 3.46-3.20 (m, 4H), 2.00 (m, 1H), 1.9-1.88 (m, 2H), 1.77-1.54 (m, 8H), 1.34-1.16 (m, 3H), 1.05-0.94 (m, 8H). 31P NMR (CD3OD, 300 MHz): δ 42.89. LCMS m/z: [M+H]+=521.
