Procedure

To a solution of 3-(2-chloro-phenyl)-3-[7-(2,6-difluoro-phenyl)-2-methanesulfonyl-7H-pyrrolo[2,3-d]pyrimidin-6-yl]-acrylic acid ethyl ester, 14, (0.30 g, 0.59 mmol)) in N-methylpyrrolidinone (4 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). After heating the reaction at 90° C. for 21 hours, an additional equivalent of 3-amino-2-methyl-butan-2-ol hydrochloride salt (0.08 g, 0.59 mmol) is added and the mixture heated at 120° C. for 4 hours. The reaction is cooled to room temp and then diluted with aqueous saturated NH4Cl solution. The aqueous phase is twice extracted with CHCl3 and the organic phase is then washed with aqueous saturated NaHCO3 solution. The organic phase is dried (MgSO4), filtered, concentrated in vacuo and the resulting residue is purified by preparative HPLC to afford the desired product as a yellowish solid: 1H NMR (300 MHz, d3-DMSO) δ 8.64 (s, 1H), 7.64-7.52 (m, 1H), 7.38-7.24 (m, 5H), 7.14-7.08 (m, 1H), 6.57 (s, 1H), 5.95 (s, 1H), 4.31 (bd s, NH), 3.85 (q, J=7.2 Hz, 2H), 3.34 (m, 1H), 1.04 (s, 9H), 0.93 (t, J=7.2 Hz); ESI+ MS: m/z (rel intensity) 541.0 (100, M++H).
