Procedure

Lithium hydroxide monohydrate (3.6 mg, 0.085 mmol) in water (0.10 mL) was added to a solution of [6-[(4-{3-(cyanomethyl)-3-[4-(7-{[2-(trimethylsilyl)ethoxy]methyl}-7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1H-pyrazol-1-yl]azetidin-1-yl}piperidin-1-yl)carbonyl]-2-(trifluoromethyl)pyrimidin-4-yl]methyl acetate (21 mg, 0.028 mmol, from Example 376, Step D) in tetrahydrofuran (0.40 mL). The mixture was stirred for 5 minutes and was then treated with 1N HCl to neutralize. Solvent was then removed in vacuo. The residue was stirred in a solution of 1:1 TFA/DCM for one hour, then solvents were removed in vacuo again. The residue was redissolved in MeOH (1 mL) and ethylenediamine (0.2 mL) was added. When deprotection was complete, the product was purified via preparative HPLC-MS (C18 eluting with a gradient of MeCN/H2O containing 0.15% NH4OH). Yield: 0.004 g (25%); LC-MS: 567.3 (M+H)+. 1H NMR (400 MHz, DMSO-d6): δ 12.14 (br s, 1H), 8.82 (s, 1H), 8.69 (s, 1H), 8.42 (s, 1H), 7.90 (s, 1H), 7.61 (d, 1H), 7.06 (d, 1H), 5.94 (br s, 1H), 4.71 (s, 2H), 4.12-4.02 (m, 1H), 3.75 (dd, 2H), 3.63-3.46 (m, 5H), 3.31-3.22 (m, 1H), 3.17-3.07 (m, 1h), 2.61-2.53 (m, 1H), 1.84-1.75 (m, 1H), 1.71-1.61 (m, 1H), 1.37-1.18 (m, 2H). 19F NMR (400 MHz, DMSO-d6): δ −69.46 (s, 3F).
