Reaction Steps

A stirred solution of N-(1-(2-(4-fluorophenyl)thiazol-5-yl)-1-(pyridin-4-yl)ethyl)acetamide (Example 69) (0.04 g, 0.12 mmol) in concentrated HCl (0.07 mL, 3.03 mmol) was heated at 100° C. for 24 hrs in a sealed glass tube. The reaction mixture was then cooled to room temperature and neutralized with 10% NaOH solution (2 mL). The aqueous layer was extracted with ethyl acetate (3×100 mL), and the combined organic layers were concentrated under vacuum. The crude product residue obtained was purified by preparative TLC using eluting solvent as MeOH:CH2Cl2 (3:7) to afford 20 mg (38%) of 1-(2-(4-fluorophenyl)thiazol-5-yl)-1-(pyridin-4-yl)ethanamine as a colorless solid. 1H NMR (400 MHz, DMSO-d6): δ 8.50 (d, 2H, J=5.6 Hz), 7.91-7.88 (m, 2H), 7.70 (s, 1H), 7.51 (d, 2H, J=6.4 Hz), 7.28 (t, 2H, J=8.8 Hz), 2.81 (s, 2H); 1.85 (s, 3H); LC-MS m/z calculated for [M+H]+300.09. found 300.1.
