Process for the preparation of 2-amino-6-halopurines |
| abstract |
Preparation of 2-amino-6-halopurines I (X = halogen) by hydrolysis of 2-acylamino-6-halopurines II (R¹, R² = acyl; R² = H) in the presence of an acid or base and preparation of II by acylation of guanine III to acylguanine Va or Vb and halogenation of V with a halogenating agent VI to II.n n n V and II are new intermediates for the synthesis of I when R1 and R2 are haloacetyl. |
