Procedure
Dissolve 1.32 gm (0.0017 mol) of the product of Step A of this example in 1.7 ml of EtOH, treat with 17 ml of 2N HCl in Et2O and stir the mixture overnight. Filter and wash the precipitate with Et2 O, recrystallize the washed material from isopropanol/water. Filter and dry the crystals (P2O5 at 79° C. at 0.1 mm) to yield 0.62 gm of the title compound, mp >300° C. Rf is 0.47 (silica gel plates eluted with 20% conc. NH3 /CH3OH).
