Reaction Steps

6-Benzenesulfonyl-7-(4-fluoro-phenyl)-2-methanesulfonyl-7H-pyrrolo[2,3-d]pyrimidine, 34, (0.04 g, 0.10 mmol) in N-methylpyrrolidinone (3 mL) is added diisopropylethylamine (0.41 mL, 2.36 mmol) and 3-amino-2-methyl-butan-2-ol hydrochloride salt (0.10 g, 0.71 mmol). The mixture is heated to 90° C. for 21 hours. The product is purified by preparative HPLC to afford 50 mg of the desired product as a yellowish solid: 1H NMR (300 MHz, d6-DMSO) δ 8.64 (s, 1H), 7.64-7.47 (m, 1H), 7.42-7.25 (m, 5H), 7.14-7.09 (m, 1H), 6.56 (s, 1H), 5.95 (s, 1H), 4.30 (s, 1H), 3.85 (q, J=7.2 Hz, 2H), 1.04 (s, 9H), 0.93 (t, J=7.2 Hz, 3H); ESI+ MS: m/z (rel intensity) 540.9 (100, M++H).
