Reaction Conditions

Reaction Steps

A solution of 2-(3-bromo-4-methoxy-phenyl)-2-methyl-propionitrile (12.71 g, 0.050 mol) in dry THF (100 mL) was cooled to −10° C. under argon. DIBALH (1M in THF, 100 mL, 0.10 mol) was added keeping the temperature below 0° C. The mixture was stirred for 30 min/0° C. and then 2 h/25° C. The clear solution was carefully poured into icecold hydrochloric acid (2M, 100 mL). The THF was removed under reduced pressure to give clear oil. The oil was destilled (b.p. 114-130° C./4.3×10−3 mbar) Yield: 7.40 g (58%). GCMS: >99%
