Reaction Steps

To a clean, dry, nitrogen-purged reactor were charged 4-chloro-7-(4-methyl-benzenesulfonyl)-7H-pyrrolo[2,3-d]pyrimidine (25.12 g, 0.082 mol), bis-(3R,4R)-(1-benzyl-4-methyl-piperidine-3-yl)-methylamine di-p-toluoyl-L-tartaric acid (40.31 g, 0.041 mol), potassium carbonate (34.2 g, 0.245 mol), and water (125.6 ml). The mixture was heated to 95-105° C. for a minimum of 10 hours, then cooled to 45-55° C. Acetonitrile (25 ml) was charged and the slurry was held at 45-55° C. for a minimum of 1 hour. The mixture was further cooled to 20-30° C. and stirred for a minimum of 5 hours. The resulting solids were isolated by filtration and washed with water (50 ml). After drying, 32.8 g (82.1%) of the title compound were isolated.
