Participants

Reaction Steps

To a solution of 1-[[4-hydroxy-1-(4,5-diphenyloxazol-2-yl)butyl]amino]-2,3-dihydro-4-methoxy-1H-indene (0.27 g) in CH2Cl2 (5 ml) was added SOCl9 (1 ml) at 0° C. After being stirred for 17 hours at room temperature, the solvent was evaporated in vacuo and the residue was dissolved in DMF (5 ml). To the mixture was added K2CO3 (2.07 g). After being stirred for 1 day at room temperature, the mixture was partitioned between ethyl acetate and water. The organic layer was washed with brine. The dried solvent was evaporated in vacuo. The residue was purified by chromatography on silica gel to give 1-[2-(4,5-diphenyloxazol-2-yl)pyrrolidin-1-yl]-2,3-dihydro-4-methoxy-1H-indene (0.15 g). MS (m/z): 437 (M+ +1) NMR (CDCl31 5) 1.42-3.20 (10H, m), 3.74 (2.5H, s), 3.81 (3.5H, s), 4.02-4.76 (2H, m), 6.58-7.72 (13H, m)
