Procedure
To a suspension of lithium aluminum hydride (1.00 g, 26.3 mmol) in 50 mL of THF at 0° C. was added 2-methyl-2-(4-nitro-phenyl)-propionic acid methyl ester (2.20 g, 9.86 mmol, Hartwig, et al, J. Am. Chem. Soc, 2004, 126, 5182) in 10 mL of THF dropwise. The resulting mixture was stirred at 0° C. for 3 h and treated with 1 mL of H2O followed by 1 mL of 15% aq NaOH and 3 mL of H2O. The solid was removed by filtration on Celite and the filtrate was concentrated in vacuo to give a light yellow oil (1.56 g, 81%). The product was used in the next step without further purification. 1H-NMR (CDCl3; 400 MHz): δ 7.92 (d, 2H, J=8.6 Hz), 7.55 (d, 2H, J=8.6 Hz), 3.69 (s, 2H), 1.40 (s, 6H).
