Versuchsvorschrift

The tyrosine phosphate derivative VIII when treated with a mixture of 0.1M hydrochloric acid and tetrahydrofuran (1:1) at room temperature for 3 hours gave less than 5% loss of the phosphate group. Treatment of compound VIII with concentrated ammonia in a sealed tube for 5 hours at 60° C. gave rise to complete removal of both 2-cyanoethyl groups with only a trace of loss of phosphate.
