Procedure
The trimethinium salt obtained in Step A (990 mg., 3 mmole) is stirred with 1N sodium hydroxide solution at 70° C. for one hour. The solid is filtered off and washed with water yielding 564 mg. (88%) of compound, m.p. 188°-190° C. (dec.). Recrystallization of the crude product from alcohol (11.5 ml.) affords the pure compound crystallizing in cream-colored prisms, m.p. 191°-192° C. with slight darkening.
