Participants

Reaction Steps

Dissolve 3-(10,11-dihydro-dibenzo[a,d]cyclohepten-5-ylidenemethyl)-phenylamine (400 mg, 1.34 mmol) in anhydrous pyridine (10 mL) and add methanesulfonyl chloride (616 mg, 416□L, 5.38 mmol). Stir overnight at room temperature, then concentrate. Take residue up in ethyl acetate and 1N HCl and separate the layers. Extract aqueous layer with ethyl acetate, combine organics, and dry (MgSO4). Concentrate to a brown oil. Purify via silica gel chromatography (2:3 ethyl acetate:hexanes) to yield 350 mg (70%) of yellow foam, mp 66.3° C. 1H NMR (CDCl3) δ 2.71 (s, 3H), 2.75-3.56 (br m, 4H), 6.09 (s, 1H), 6.64-7.43 (m, 13H); MS (ES) 398 (M+23), 374 (M−H). HPLC shows 96% purity.
