Reaction Steps
To 100 mg (0.14 mmol) of the amine from Example 40 in 2 mL of EtOH was added 16 mg (0.15 mmol) of benzaldehyde. The reaction mixture was heated to 60° C. for 1 hour, cooled to 0° C. and treated with 0.29 mL (0.29 mmol) of a 1M solution of NaCNBH3 in THF. The reaction mixture was stirred overnight, concentrated in vacuo, and the residue partitioned between 25 mL of EtOAc and 15 mL of water. The phases were separated and the organic phase was washed with brine (1×25 mL) and dried over MgSO4. The mixture was filtered and concentrated in vacuo and the residue was purified by flash chromatography over silica gel eluting with 25% EtOAc/hexanes to give 45 mg (0.06 mmol) of a yellow foam. 1H-NMR (CDCl3 300 MHz): 0.88 (t, 3H, J=7.4 Hz), 1.31 (m, 2H), 1.66 (m, 2H), 2.61 (3 line m, 2H, J=7.8 Hz), 4.32 (bs, 1H), 4.43 (bs, 2H), 5.28 (bs, 2H), 6.88 (m, 8H), 7.08 (m, 3H), 7.20-7.53 (m, 19H), 7.91 (d, 1H).
