実験手順

To a solution of 10.00 g (4R,9aR)-6-Formyl-4-methyl-3,4,9,9a-tetrahydro-1H-2,4a,5-triaza-fluorene-2-carboxylic acid tert-butyl ester in 100 ml tetrahydrofuran was added drop wise at 0° C. 20 ml of a ca 3M solution of methyl magnesium bromide solution in ether. The mixture was stirred at 0° C. for 30 min. The reaction mixture was quenched with 10% aqueous ammonium chloride and extracted with ethyl acetate. The organic phase was washed with 105 aqueous citric acid, 10% aqueous sodium bicarbonate and brine, dried over sodium sulfate, evaporated and dried to constant weight under high vacuum to yield 10.0 g of the title compound as colorless oil (MS: 334.5 (M+H+)).
