実験手順

A solution of 300 mg (1.00 mmol) of Compound P from step E was dissolved in 20 mL acetonitrile and 0.40 mL (5.3 mmol) 37% aqueous formaldehyde was added followed by 0.10 grams (1.59 mmol) sodium cyanoborohydride. After 30 minutes, the solution was brought to pH 7 by dropwise addition of glacial acetic acid then stirred an additional 1 hour and 45 minutes. The solvent was removed under reduced pressure, and the residue was taken up into 125 mL ethyl acetate. This was washed with 50 mL 10% sodium bicarbonate, dried (MgSO4) and evaporated to give an oil, which was purified by flash chromatography over silica gel, eluting with ethyl acetate to give 150 mg of trans-5,6,7,7a,8,12b-hexahydro-2-methoxy-3-chloro-7-methyl-benz[d]indeno[2,1-b]azepine (Compound Q) as an oil, 200 MHz NMR (CDCl3) d 2.17(dd,1H,J=12,Hz), 2.69(m,2H) 2.37(s,3H), 2.90-3.40(m,4H), 3.77(s,3H), 4.67(d,1H,J=9 Hz), 7.03(s,1H), 7.17(s,1H), 7.20-7.35(m,4H).
