Reaction Steps

To a −78° C. solution of 1-(1-ethyl-propyl)-6-methyl-4-(2,4,6-trimethyl-phenoxy)-1,3-dihydro-pyrrolo[3,2-c]pyridin-2-one (352 mg, 1.0 mmol) in 2 ml of dry THF was added 2.5M BuLi in hexane (0.4 mmol, 1.0 mmol). The resulting mixture was stirred at −78° C. for 30 min, then transferred to a −78° C. solution of methyl iodide (3 ml) in 3 ml of dry THF. The resulting mixture was stirred at −78° C. for 1 hour, quenched with saturated ammonium chloride, extracted with ethyl acetate. The organic layer was dried and concentrated to give a clear oil which was purified through silica gel column chromatography using hexane to 10% ethyl acetate in hexane as eluent to give the title compound as tan solid 214 mg (68%). 1H NMR (CDCl3) δ 6.88 (s,2H), 6.47(s,1H), 4.1(m,1H), 3.56(q,1H), 2.30(s,3H), 2.26(s,3H), 2.07(s,6H), 1.7–2.0(m,4H), 1.60(d,3H), 0.86(t,6H) ppm.
