Subsequently, the reaction mixture was stirred for 2 hours at room temperature, then water was added, and the tetrahydrofuran was distilled off in vacuo. The oil thus obtained as a residue crystallized after some time and was recrystallized from methanol/water, yielding 2.7 gm of the compound of the formula ##STR5## having a melting point of 135° C.
