To a high pressure vessel is added compound 9 (1.70 kg, 2.567 mol) in THF (5 L), followed by an ammonia/isopropyl alcohol solution (30.80 mol of ammonia in 12 L of isopropyl alcohol). The mixture is heated to 100° C. overnight. When the reaction is completed, the solvents are removed in vacuum and the residue is dissolved in isopropanol. Compound 10 is isolated and further purified by recrystallization using a mixture of THF (7 L) and isopropanol (14 L). Yield: 0.763 kg (60.7%).
