Reaction Steps

Methanesulfonyl chloride (2.8 0.036 mmol) in methylene chloride (0.20 mL) was added to a mixture of {1-(1-{[6-(hydroxymethyl)-2-(trifluoromethyl)pyrimidin-4-yl]carbonyl}piperidin-4-yl)-3-[4-(7-{[2-(trimethylsilyl)ethoxy]methyl}-7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1H-pyrazol-1-yl]azetidin-3-yl}acetonitrile (21 mg, 0.030 mmol, prepared as in Example 376, Step E) and triethylamine (8.4 μL, 0.060 mmol) in methylene chloride (1.0 mL) at 0° C. After 15 minutes, 2-propanamine (20 μL, 0.3 mmol) was added. The mixture was then heated to 40° C. After 1.5 hours, additional 2-Propanamine (20 μL, 0.3 mmol, Aldrich) was added and the reaction heated for a total of 3 hours at this temperature. The mixture was concentrated in vacuo. The residue was stirred for 1 hour in a 1:1 mixture of TFA/DCM, then concentrated again. The residue was redissolved in MeOH (1.0 mL) and ethylenediamine (0.2 mL) was added. The product was purified via preparative HPLC-MS (C18 eluting with a gradient of MeCN/H2O containing 0.15% NH4OH). Yield: 11.6 mg (63%); LC-MS: 608.4 (M+H)+. 1H NMR (400 MHz, DMSO-d6): δ 12.15 (br s, 1H), 8.82 (s, 1H), 8.69 (s, 1H), 8.42 (s, 1H), 7.97 (s, 1H), 7.61 (d, 1H), 7.07 (d, 1H), 41.2-4.02 (m, 1H), 3.94 (s, 2H), 3.75 (dd, 2H), 3.63-3.45 (m, 5H), 3.31-3.22 (m, 1H), 3.16-3.06 (m, 1H), 2.75 (septet, 1H), 2.61-2.53 (m, 1H), 1.84-1.75 (m, 1H), 1.70-1.60 (m, 1H), 1.36-1.19 (m, 2H), 1.01 (d, 6H). 19F NMR (400 MHz, DMSO-d6): δ −69.46 (s, 3F).
