Procedure

For the preparation of the starting material compound 29.2, please see Example 29. A solution of 2-[(3R)-12-[[4-(morpholin-4-yl)cyclohexyl]oxy]-7-thia-9,11-diazatricyclo[6.4.0.0[2,6]]dodeca-1(8),2(6),9,11-tetraen-3-yl]ethan-1-ol (190 mg, 0.47 mmol, 1.00 equiv) in 10 mL of dichloromethane was added Dess-Martin periodinane at 0° C. in a water/ice bath under nitrogen. The resulting mixture was stirred for 2 h at room temperature. After completion of the reaction, the mixture was then diluted with saturated aqueous sodium bicarbonate and extracted with 3×30 mL of ethyl acetate. The combined organic layers were dried over sodium sulfate and concentrated under vacuum. The residue was applied onto a silica gel column with ethyl acetate/petroleum ether (1:5 to 1:1) to afford 2-[(3R)-12-[[4-(morpholin-4-yl)cyclohexyl]oxy]-7-thia-9,11-diazatricyclo[6.4.0.0[2,6]]dodeca-1(8),2(6),9,11-tetraen-3-yl]acetaldehyde (130 mg, 69%) as a colorless oil. MS (ES): m/z 402 [M+H]+.
