Participants

Reaction Steps

Prepared from 70 mg (0.16 mmol) of 1-cyclopentyl-7-{3-methyl-4-[2-(diethylamino)ethoxy]phenylamino}-3,4-dihydro-pyrimido[4,5-d]pyrimidin-2(1H)-one and 72 mg (0.58 mmol) of potassium tert-butoxide in 3.0 mL of DMSO. The crude semi-solid residue is dissolved in a mixture of tert-butyl methyl ether and hexane. The solution is allowed to evaporate slowly to less than 1 mL, then diluted with 2 mL of 1:3 diethyl ether/hexane. The precipitated solids are collected and dried to give 17 mg (24%) of the title compound: mp>95° C. (dec).
