Procedure
To a stirred solution of 33 (0.6 g. 2.6 mmol) in 20 ml of anhydrous pyridine was added 0.9 g (2.66 mmol) of DMTCl. After being stirred at room temperature for 5 hrs the reaction was quenched with methanol (3 ml), concentrated and portioned between 10% citric acid and ethyl acetate. The organic phase was washed with saturated NaCl, dried over Na2SO4 and concentrated in vacuo to a solid foam. The crude product was chromatographed on silica eluting with ethyl acetate to afford 0.95 g (69%) of 34 as an amorphous white solid. 1H NMR (DMSO-d6): δ 11.16 (s, 1H), 7.28 (m, 6H), 7.21 (m, 4H), 6.85 (m, 4H), 4.59 (d, J=5 Hz, 1H), 3.76 (m, 2H), 3.74 (s, 6H), 3.57 (m, 1H), 3.10 (m, 1H), 2.95 (m, 1H), 2.11 (m, 1H), 1.67 (s, 3H), 1.02 (d, J=6.3 Hz, 3H).
