Participants

Reaction Steps

3.6 g (9.6 mmol) of the compound (1) of Working Example 41 was dissolved in 30 ml of 70% aqueous acetonitrile, and to the solution was added 2.0 g (15.9 mmol) of oxalic acid dehydrate. The mixture was dissolved under heating, and then cooled. The resulting crystals were recrystallized from 70% aqueous acetonitrile to obtain 4.0 g of colorless crystals having a melting point of 95 to 98° C.
