Procedure

To a solution of N-(5-amino-2-chloropyridin-3-yl)methanesulfonamide (60 mg, 0.271 mmol) and 4-(2-fluoro-5-(tetrahydro-2H-pyran-4-yl)pyridin-3-yl)-6-methyl-1,3,5-triazin-2-amine (55 mg, 0.190 mmol) in anhydrous DMF (1 mL) cooled in an ice bath was added solid NaHMDS (210 mg, 1.088 mmol) under nitrogen. The resulting orange mixture was stirred with cooling. After 1.5 h, HCl (5N, 0.25 mL, 1.25 mmol) was added to the mixture. The resulting mixture was diluted with water (5 mL) and acidified with HCl, 5N) to about pH 5. The resulting slurry was filtered and washed with water (3×3 mL). The solid was washed with EtOAc to afford the product as a brown solid. The mother liquid was chromatographed on silica gel (0-5% MeOH in EtOAc) to give additional product. The combined product was about mg (32%). m/z (ESI, positive ion): 491.1 (M+H)+. 1H NMR (400 MHz, DMSO-d6) δ ppm 1.60-1.82 (m, 4H) 2.46 (s, 3H) 2.84 (t, J=11.35 Hz, 1H) 3.12 (s, 3H) 3.46 (t, J=10.76 Hz, 2H) 3.97 (d, J=12.13 Hz, 2H) 7.78 (br. s., 1H) 7.92 (br. s., 1H) 8.33 (s, 1H) 8.64 (d, J=3.33Hz, 2H) 8.72 (s, 1H) 9.64 (br. s., 1H) 12.17 (s, 1H).
