Dimethyl Sulfoxide → HCID 59750672, compound

Participants

Reaction Steps

Combine DCM (3 mL) and oxalyl chloride (41 uL) under nitrogen atmosphere at −78° C., and then add DMSO (49 uL) in DCM (2 mL). After the solution stirs for 15 minutes, add 6-(2-Hydroxymethyl-indan-5-yloxy)nicotinamide (33.1 mg, 0.116 mmol) in DCM (2 mL). After 15 minutes, add Et3N (97 uL, 0.70 mmol). After the reaction gradually warms to room temperature over the next 5 hours, then quench with water. Add the mixture to a separatory funnel and extract the product with DCM. Wash the organic phase with brine and then dry over Na2SO4. After concentrating under reduced pressure, flash chromatograph using 10% THF/CH2Cl2 eluent affords 27.4 mg, 0.10 mmol (84% yield) of the title compound: 1H NMR (500 MHz, CDCl3); 3.1-3.2 (2H, m), 3.2-3.4 (3H, m), 6.8-7.0 (4H, m), 7.1-7.3 (1H, m), 8.8-8.9 (1H, m), 8.4 (1H, s), 9.7 (1H, s); TLC 1:6 THF:CH2Cl2Rf:=0.7.
