Reaktionsschritte

S5; 3-{4-[N′-(3-methyl-benzylidene)-hydrazino]-6-morpholin-4-yl-pyrimidin-2-yl}-propan-1-ol (355 mg, 1 mmol) was dissolved in acetonitrile (4 mL). To the mixture was added m-methoxyphenylisocyanate (149 mg., 1 mmol) and a catalytic amount of dimethylaminopyridine. The reaction was stirred at 60° C. for 16 hours. The reaction was then cooled to 4° C., and the precipitate was filtered, washed with acetonitrile (1 mL) and dried to give Compound 1, (3-methoxy-phenyl)-carbamic acid 3-{4-[N′-(3-methyl-benzylidene)-hydrazino]-6-morpholin-4-yl-pyrimidin-2-yl}-propyl ester.
