Procedure
In the same way as in [A] and reacting the N-(3,4-dimethoxyphenyl)glycine (17.2 g, 81 mmoles) with potassium cyanate (6.6 g, 81 mmoles) the 1-(3,4-dimethoxyphenyl)hydantoin was obtained, m.p. 223°-225° C. By reacting the latter (11.23 g, 47.5 mmoles) with 2-bromoethylamine hydrobromide (9.74 g, 47.5 mmoles) as described in [A] the title compound was obtained, m.p. 162°-164° C.
