HCl (35.274 of 3 M, 0.1058 mmol) was added to a solution of N-[(1S)-1-[4-[5-[3-amino-6-(4-isopropylsulfonylphenyl)pyrazin-2-yl]-1,3,4-oxadiazol-2-yl]phenyl]-2,2,2-trifluoro-ethyl]-2-methyl-propane-2-sulfinamide (253.3 mg, 0.05288 mmol) in MeOH (1 mL) and the resulting solution stirred at room temperature overnight. The reaction mixture was concentrated to dryness under reduced pressure and the residue triturated with acetonitrile and filtered. The solid was taken up in a mixture of acetonitrile/water/MeOH and passed through the bicarbonate cartridge. The eluent was concentrated in vacuo and then triturated with acetonitrile to give the product as a yellow solid (26 mg, 99% yield); 1H NMR (400.0 MHz, DMSO) d 1.20 (d, 6H), 2.68 (d, 2H), 3.41-3.51 (m, 1H), 4.65-4.75 (m, 1H), 7.81 (d, 2H), 7.98 (d, 2H), 8.20 (d, 2H), 8.41 (d, 2H) and 9.08 (s, 1H) ppm; MS (ES+) 519.1
