Reaction Steps

BH3-DMS (0.56 g, 7.4 mmol) was added dropwise to a solution of hydroxynitrile (14) (0.65 g, 2.4 mmol) in dry THF (50 mL). The reaction mixture was refluxed 18 h at 65° C. After completion of the reaction (as monitored by TLC) the MeOH (15 mL) was added to the reaction mixture which was stirred at rt for an additional 1 h. The mixture was then concentrated under reduced pressure followed by purification by column chromatography (100-200 silica mesh, 4-6% MeOH in DCM) to give Example 1 as a white solid. Yield (0.75 g, 99%); 1H NMR (400 MHz, DMSO-d6) δ 7.80 (bs, 3H), 7.24 (t, J=8.0 Hz, 1H), 6.89-6.87 (m, 2H), 6.82-6.80 (m, 1H), 5.54 (bs, 1H), 4.65 (bs, 1H), 3.87 (dd, J=11.4, 2.8 Hz, 2H), 3.81 (d, J=6.4 Hz, 2H), 3.37-3.30 (m, 2H), 2.87-2.79 (m, 2H), 2.02-1.96 (m, 1H), 1.88-1.80 (m, 2H), 1.69-1.65 (m, 2H), 1.34-1.27 (m, 2H); RP HPLC tR=1.10 min, 94.5% (AUC); ESI MS m/z 266.27 [M+H]+.
