Reaction Conditions

Reaction Steps

To a stirred solution of 243 (0.08 g, 0.236 mmol) in toluene was added PTSA (0.090 g, 0.472 mmol) and kept stirring at 120° C. Hexafluoroacetone 244 (0.129 g, 0.590 mmol) was added to the reaction and heated to 100° C. for 16 h. Reaction was cooled to RT, diluted with water, extracted with ethyl acetate twice, the organic layer dried over sodium sulphate and concentrated to get the crude, which was purified through flash chromatography by using 100-200 mesh silica gel eluting the compound at 30% ethyl acetate in hexane as thick sticky solid 2-((5-(1,1,1,3,3,3-hexafluoro-2-hydroxypropan-2-yl)pyridin-3-yl)methyl)-6-methoxy-5-morpholino-2,3-dihydro-1H-inden-1-one 245. 1HNMR (400 MHz, CDCl3) δ ppm 7.06 (m, 2H), 6.88 (s, 1H), 6.90 (s, 1H), 6.123 (s, 1H), 3.88 (m, 7H), 3.49 (m, 1H), 3.08 (m, 2H), 3.03 (m, 6H), 2.29 (m, 2H).
