Procedure
A solution of the product from Example 27 (185 mg, 0.44 mmol) in DMF (3 mL) was treated with methane sulfonic acid (30 μL, 0.46 mmol) and stirred at room temperature for 40 hours. The solids were filtered off, washed with DMF and dried to give the first batch of the title compound (39 mg) as a grey solid. The filtrate was concentrated under vacuum, triturated with acetone. The precipitate was then filtered and dried to give the second batch of the title compound (104 mg) as a pale yellow solid, mp=220-225° C., 46% total yield.
