To a solution of 13 (0.1 g, 0.40 mmol)), MeOH/H2O (1:1), was added 5-(1,1,1,3,3,3-hexafluoro-2-hydroxypropan-2-yl)nicotinaldehyde 259 (0.132 g, 0.485 mmol) and NaOH (0.032 g, 0.80 mmol). The reaction was stirred at RT for 6 h. The reaction mass was diluted with chloroform and washed with water (3×25 ml). The organic layer was dried over sodium sulphate and concentrated to get the crude 263, which was purified through flash chromatography by using 100-200 mesh silica gel. The compound was eluted at 30% ethyl acetate in hexane to afford yellow coloured solid (E)-2-((5-(1,1,1,3,3,3-hexafluoro-2-hydroxypropan-2-yl)pyridin-3-yl)methylene)-6-methoxy-5-morpholino-2,3-dihydro-1H-inden-1-one 263.
