Acrylic Acid → HCID 90461841, compound

Participants

Reaction Steps

A mixture of tert-butyl 3-(4-(2-(4-chloro-5-isopropyl-2-methoxyphenylamino)acetyl)piperazin-1-yl)azetidine-1-carboxylate (102 mg, 0.212 mmol) in HCl/MeOH (2.86 M, 5 mL) was stirred at RT for 1 h. The mixture was concentrated in vacuo to afford the crude product, the crude was dissolved in DMF (5 mL) at RT, acrylic acid (17 mg, 0.233 mmol), BOP (113 mg, 0.254 mmol) and DIEA (82 mg, 0.636 mmol) were added and the resulting mixture was stirred at RT for 1 h. The mixture was partitioned between ethyl acetate and water. The organic layer was washed brine, dried over MgSO4, filtered and concentrated in vacuo. The residue was purified by flash column chromatography on silica gel (dichloromethane/methanol=50:1) to afford the desired product (77 mg, 85% yield, 2 steps). ESI-MS m/z: 435.4[M+H]+.
