Reaction Steps

Title compound G, 4-{4-[2-Cyclopentyl-1-(5-morpholin-4-yl-thiazolo[5,4-b]pyridin-2-ylcarbamoyl)-ethyl]-benzenesulfonyl}-piperazine-1-carboxylic acid tert-butyl ester (0.26 g, 0.378 mmol) was dissolved in 5 mL DCM and 2 mL of TFA was added. The solution was stirred for 1 h and then evaporated to afford a crude oil. The residue was partitioned between 2N NaOH and ethyl acetate and extracted numerous times with ethyl acetate, dried over MgSO4, filtered and concentrated to afford a green solid. This material was taken on crude to the next reaction. 1H NMR (400 MHz, DMSO) δ 1.07-1.16 (M, 2H) 1.39-1.50 (m, 2H) 1.52-1.63 (m, 3H) 1.68-1.79 (m, 3H) 2.16 (m, 1H) 2.71 (d, J=4.80 Hz, 4H) 2.76 (d, J=5.05 Hz, 4H) 3.43-3.51 (m, 4H) 3.67-3.74 (m, 4H) 4.07 (d, J=8.84 Hz, 1H) 6.97 (d, J=9.09 Hz, 1H) 7.64-7.69 (m, 2H) 7.69-7.73 (m, 2H) 7.88 (d, J=9.09 Hz, 1H) MS 585.31 [M+1]+.
