To a solution of tert-butyl 4-[N-[4-oxo-2-(piperidin-1-yl)methyl-3,4,7,8-tetrahydro-6H-cyclopenta[g]quinazolin-6-yl]-N-methylamino]benzoate (0.060 g, 0.123 mmol) in anhydrous DMF (3 ml) under argon was added a dispersion of NaH in mineral oil (60% w/w) (0.0060 g, 0.147 mmol) and the reaction mixture was stirred for 1 min. Mel (15 μL, 0.246 mmol) was then added via syringe and the reaction mixture was stirred for a further 2 hours. The reaction mixture was then partitioned between a saturated aqueous solution of sodium bicarbonate (40 ml) and ethyl acetate (75 ml) and the organic phase was then successively washed with a saturated aqueous solution of sodium bicarbonate (30 ml), brine (30 ml), then dried (Na2SO4) and concentrated under reduced pressure to afford the title compound (0.056 g, 91%).
