Reaction Steps

Compound 93, 2-{4-[N′-(3-methyl-benzylidene)-hydrazino]-6-morpholin-4-yl-pyrimidin-2-yl}-ethanol (680 mg., 2 mmol) was dissolved in methylene chloride (10 mL) and to the reaction mixture was added diisopropylethylamine (0.6 mL, 3 mmol). The reaction was chilled to 0° C. To the reaction was added methanesulfonyl chloride (251 mg., 2.2 mmol). After fifteen minutes, the reaction was washed with saturated aqueous ammonium chloride (2×2 mL), dried with sodium sulfate, and purified by column chromatography to give Compound 95, methanesulfonic acid 2-{4-[N′-(3-methyl-benzylidene)-hydrazino]-6-morpholin-4-yl-pyrimidin-2-yl}-ethyl ester (290 mg., 0.7 mmol).
