Procedure

[4-(Benzyloxy)-2-cyanophenyl]acetic acid (0.40 g, 1.50 mmol) was dissolved in DMF (5 ml) and azetidine (0.128 g, 2.25 mmol), DIEA (0.78 ml, 4.49 mmol), and HATU (1.14 g, 2.99 mmol) added. The mixture was stirred at RT for 1 hr. The solution was loaded directly onto a Biotage RP C18 cartridge (30 g) and purified using a gradient eluant of 10-100% water:acetonitrile+0.05% formic acid. The volatiles were removed in vacuo to afford the title compound. LC/MS (m/z): 307 (M+H)+.
