Reaction Steps

2-Amino-1-methyldibenzothiophene (Method 10; 0.337 g, 1.58 mmol), 4-(dimethylamino)pyridine (0.213 g, 1.74 mmol), EDAC (0.334 g, 1.74 mmol) and tetrahydro-3-furoic acid (0.167 ml, 1.74 mmol) were stirred in DCM (20 ml) at reflux under an argon atmosphere for 64 h. The product was purified by flash chromatography eluting with DCM-5% methanol/DCM. Evaporation of the appropriate fractions gave the product as a white solid. NMR: 9.77 (brs, 1H), 8.44 (m, 1H), 8.04 (m, 1H), 7.82 (d, 1H), 7.52 (m, 2H), 7.36 (d, 1H), 4.00 (m, 1H), 3.76 (m, 3H), 3.27 (m, 1H), 2.68 (s, 3H), 2.15 (q, 2H); m/z 313.
