Reaction Steps

57.4 g of N′-[2-(3-hydroxyphenyl)acetyl]-4-benzyloxy-2-ethylbenzohydrazide are dissolved in 1.5 l of THF and hydrogenated for 24 h. The catalyst (5% Pd/C, 35 g) is added in 3 portions. The catalyst is filtered off with suction, the solution is evaporated, and the residue is crystallised from MeCN, giving 41.1 g of “60” (92%); m.p. 199-200°.
