実験手順

1.8 g of ethyl 2-[4-[((3S)-1-tert-butoxycarbonyl-3-pyrrolidinyl)oxy]phenyl]-3-(5-cyano-2-benzofuranyl)-propionate was dissolved in 28 ml of formic acid, and the solution was stirred at 70° C. for 1 hour. The resulting reaction solution was concentrated to dryness, and the residue thus obtained was dissolved in 8 ml of formic acid. 0.29 ml of 37% formaldehyde was added thereto, and then refluxed under heating for 4 hours. After cooling, the reaction solution was mixed with chloroform, and then adjusted to pH 10-11 with aqueous ammonia, and the resulting organic layer was collected and dried.
