실험 절차

A mixture of 2,7-diamino-6-(2,6-dichlorophenyl)-pyrido[2,3-d]pyrimidine (4.00 g) from Example 1, sulfamic acid (2.53 g) and aminopropylmorpholine (30 mL) was reacted as in Example 53. In this instance, the crude residue was washed with hot ethyl acetate followed by diethyl ether to afford 3.95 g of the title compound 6-(2,6-dichlorophenyl)-N2 -(3-morpholin-4-yl-propyl)-pyrido[2,3-d]pyrimidine-2,7-diamine, CIMS (1% NH3 in CH4): 461=M+ +C2H5, 433=M+ +H (Base), 346, 332; mp 224-230.5° C.
