Reaction Steps

A suspension of Raney®-Nickel in a methanolic solution of 5b (0.76 g in 50 ml, 1.98 mmol) was shaken under 50 psi of hydrogen atmosphere for 12 hours. The mixture was filtered and the filtrate was concentrated and used for the next step without further purification (0.69 g, 1.96 mmol, 99%).
