Procedure

160 (100 mg, 0.315 mmol) is dissolved in 4 ml of methanol and treated with a solution of NaOH (1 ml, 2N). The mixture is stirred 1 hour at room temperature. The reaction mixture is acidified with HCl (1 ml, 2N) and evaporated. The crude mixture is used in the next step without further purification.
