Reaction Steps

To a solution of 2-(2-chloro-phenyl)-1-[7-(4-fluorophenyl)-2-methanesulfonyl-7H-pyrrolo[2,3-d]pyrimidin-6-yl]-ethanone, 31, (0.036 g, 0.080 mmol) in N-methylpyrrolidinone (2 mL) is added diisopropylethylamine (0.071 mL, 0.410 mmol) and 3-amino-2-methyl-butan-2-ol hydrochloride salt (0.035 g, 0.240 mmol). The mixture is heated to 120° C. for 4 hours. The reaction crude product is then purified by preparative HPLC to afford the desired product as a yellowish solid: 1H NMR (300 MHz, CDCl3) δ 8.60 (s, 1H), 7.54 (s, 1H), 7.42-7.38 (m, 1H), 7.32-7.10 (m, 7H), 4.36 (s, 2H), 3.92-3.82 (m, 1H), 1.26 (d, J=9.1 Hz, 6H), 1.20 (d, J=6.8 Hz, 3H); ESI+ MS: m/z (rel intensity) 467.0 (100, M++H).
