Bees - was it not discussed previously that one of the reasons this rxn was not performing well was that bees were skipping the sonification step???
Uemura - why not simply reduce ala ab2? it works well. i'm sure you have you reasons so heres your early xmas present,
Tetrahedron Lett, Vol 26, No52, pp6413-6416, 1985
A 100ml rb flask containing NiCl2-6H20(1.55mmol) and CH3OH (30 mls) 2was
sonicated to effect complete solution, then solid NaBH4 (4.65mmol) was added portionwise (frothing!!!). After 30 min nitro (3.1mmol) was added in 2ml CH3OH, followed by more solid NaBH4 (10.9mmol) over 5 minute period, five minutes later tlc indicated all nitro compound had disappeared - i'll leave the work-up to your imagination
