실험 절차
Dibenzo[b,d]furan-2-ylmethanol CCH 34116 (174 mg, 878 μmol) was immediately dissolved in dry CH2Cl2 (10 mL) in a 20 mL microwave vial equipped with a magnetic stirrer before slow addition of SOCl2 (1.0 mL, 13.78 mmol) and the reaction mixture was stirred for 20 min at 80° C. under microwave irradiation. After cooling to RT, the volatiles were removed at 40° C. under vacuum. The residue was taken up in CH2Cl2 (20 mL) before concentration back to dryness at 40° C. under vacuum (done 3 times) to give 2-(chloromethyl)dibenzo[b,d]furan CCH 34116-2 as a grey solid (189 mg, 99% yield).
