Sodium Bicarbonate → HCID 86651670, compound

Participants

Reaction Steps

To a suspension of N-{2-[3,4-dichloro-5-(hydroxymethyl)phenyl]ethyl}propanamide (1 eq.) from the previous step and sodium bicarbonate (1.1 eq.) in dichloromethane (0.1 M) was added DMP (1.1 eq.) at 0° C. The resulting mixture was stirred at RT for 2 h before it was quenched with sat. aq. NaHSO3 and then extracted with Et2O. The combined organic extracts were washed further with 1 N aq. NaOH, water and brine, dried over Na2SO4, filtered and the filtrate concentrated in vacuo. Purification of the crude product thus obtained by way of flash chromatography (SiO2, 19:1 (v/v) Hex:EtOAc→3:7 (v/v) Hex:EtOAc) afforded the title compound as a white solid.
