Compound A (9.0 g, 0.05 mol) was dissolved in 200 ml of methanol and hydrogenated with Raney nickel catalysis under 1 atm of hydrogen. After hydrogen uptake ceased, the catalyst was filtered off with suction, and the solvent was removed in vacuo. The solid product was stirred with diethyl ether, resulting in 2.4 g of pure product (melting point 236°-237° C.).
