Procedure
Combine 3-methyl-butylaldehyde (26 μl, 0.24 mmol), amine from step 6 above and 3 A molecular sieves (900 mg) in methanol (3 mL), stir the mixture at room temperature overnight. Add NaBH4 (45 mg, 1.20 mmol) and stir at room temperature for 3 hours. Filtrate the mixture over celite and eliminate the solvent. Submit the crude to a SCX column to obtain a solid which was further purified by HPLC (Column: X-Terra MS C18. A=10 Mm NH4HCO3 pH8/B═CH3CN. Gradient mode: from 30 to 70% B. Flow rate: 1 mL/min) to obtain the title compound (42 mg). Electrospray MS M+1 ion=364. 1H-NMR (metanol-d4, 300 MHz): 8.60 (d, 1H, J=2.0 Hz), 8.32 (dd, 1H, J=2.2 and 8.5 Hz), 7.19 (d, 1H, J=8.7 Hz), 7.01-6.98 (m, 2H), 2.85 (m, 4H), 2.63 (m, 2H), 1.62 (m, 1H), 1.42 (q, 1H, J=7.3 Hz), 0.92 (d, 6H, J=6.5 Hz).
