Reaction Steps

80 μl of NaOH, 1M, were added to 15 mg of 3-(1-benzylindazole-3-carboxamido)-1,1-dichlorobut-1-ene (40 μmol) in 20 μl of N-methylpyrrolidone under argon and the mixture was heated at 55° C. for 1 hour. It was cooled and 0.8 ml of water and 8 ml of ethyl acetate were added. The organic phase was concentrated and the residue was purified by preparative TLC (SiO2). 9.9 mg (77%) of 2-(1-benzylindazol-3-yl)-5-hydroxymethyl-4-methyl-oxazole were obtained (melting point 127-129° C.).
