A solution of 2.33 g (5.7 mmol) of the compound from Example 47A in 18 ml of tetrahydrofuran was added dropwise to 20.1 ml (60.1 mmol) of a 1N solution of lithium aluminum hydride in tetrahydrofuran and 20 ml of tetrahydrofuran at RT. The mixture was stirred at 60° C. for 1 h, acetonitrile was added, and water was added to the solution while cooling in ice. The solid was filtered off with suction from the suspension, the filtrate was concentrated, and the residue was purified by preparative HPLC (mobile phase: acetonitrile/water gradient). 1.72 g (82% of theory) of the title compound were obtained.
