Procedure:
To a solution of diisopropylamine (2.70 ml, 18.96 mmol) in THF (20 ml), BuLi in hexanes (11.85 ml, 18.96 mmol) was added under nitrogen at 0° C. After stirred for 0.5 hour at the same temperature, the solution was cooled to −78° C. and then a solution of benzyl 3-(biphenyl-4-yl)propanoate (5 g, 15.80 mmol) in THF (20 ml) was added. After stirred for 1.5 hour at the same temperature, tert-butyl bromoacetate (3.33 ml, 22.12 mmol) was added, and then the mixture was warmed up to 0° C. The reaction mixture was allowed to stir at 0° C. for 2 hours, and then stirred at room temperature for 14 hours. The reaction mixture was poured into 150 ml of saturated aq. NH4Cl. The product was extracted twice with EtOAc. The combined organic layer was washed with brine, dried over MgSO4, filtered, and concentrated under reduced pressure. The obtained residue was purified by flash column chromatography on silica gel (eluent: heptane/EtOAc=100:0 to 10:1) to give the 1-benzyl 4-tert-butyl 2-(biphenyl-4-ylmethyl)succinate (2.97 g); Retention time=1.00 minutes (condition G); MS (m+1)=431.2.

Procedure:
A mixture of 4-(diethylamino)salicylaldehyde (10 g, 52 mmol, obtained from Aldrich) dissolved in 80 ml of 2-propanol, and N-methyl-N-phenylhydrazine (6.8 ml, 63 mmol, obtained from Aldrich) was added to a 250 ml round bottom flask equipped with a reflux condenser and a magnetic stirrer. The reaction mixture was refluxed until 4-(diethylamino)salicylaldehyde completely reacted. After the termination of the reaction, the reaction mixture was cooled to room temperature. The crystals formed were filtered and washed repeatedly with cold 2-propanol and dried under vacuum to yield 12.9 g (84%) of 4-(diethylamino)salicylaldehyde N-methyl-N-phenylhydrazone. The melting point was found to be 75.5–76.5° C. (recrystallized from 2-propanol). The 1H-NMR spectrum (100 Mhz) of the product in CDCl3 was characterized by the following chemical shifts (in ppm): 11.53 (s, 1H, OH); 7.63 (s, 1H, N═CH); 7.50–6.80 (m, 6H, Ar); 6.26 (m, 2H, Ar); 3.37 (m, 7H, CH2CH3, NCH3); 1.18 (t, 6H, CH2CH3, J=7.0 Hz). An elemental analysis yielded the following results in weight percent: C, 72.61; H, 7.88; N, 14.20, which compared with calculated values for C18H23N3O in weight percent of: C, 72.70; H, 7.80; N, 14.13.
