Reaction Steps

A mixture of 4-(7-methyl-2,4-di-1-pyrrolidinyl-7H-pyrrolo- 2,3-d!pyrimidin-6-yl)phenylamine (EXAMPLE 188, 206 mg) in 40 ml of dichloromethane is cooled in an ice-water bath and treated with 0.15 ml of triethylamine followed by 0.05 ml of methanesulfonyl chloride. Three additional portions of methanesulfonyl chloride, 0.02 ml, 0.01 ml and 0.01 ml, are added in sequence over the next hour. The mixture is poured onto water, treated with aqueous saturated sodium bicarbonate and extracted with three portions of dichloromethane. The combined organic extracts are dried and concentrated to give a solid which is combined with previously isolated material (from a 50 mg run) and chromatographed over silica eluting with methanol/chloroform (3/97) to give the desired material which is recrystallized from hot acetonitrile to give the title compound, mp 245-248; NMR 7.49-7.47, 7.31-7.28, 6.42, 3.78-3.69, 3.64, 3.58-3.52, 3.36, 1.97-1.85δ.
