Participants

Reaction Steps

6.5 g (16.2 mmol) of the compound (1) of Working Example 38 was dissolved in 50 ml of 30% aqueous acetonitrile, and 3.0 g (23.8 mmol) of oxalic acid dihydrate was added thereto. The mixture was dissolved under heating, and then cooled. The resulting crystals were recrystallized from 50% aqueous acetonitrile to obtain 2.9 g of colorless crystals having a melting point of 101 to 103° C.
