Procedure

1-(4-Nitrophenyl)pyrroidin-3-ol and methanesulfonyl chloride were allowed to undergo the reaction in THF in the presence of triethylamine. The resulting compound and sodium cyanide were allowed to undergo the reaction in 1-methyl-2-pyrrolidone under heating. The resulting compound was subjected to catalytic hydrogenation in the same manner as shown in Reference Example 3 to obtain 1-(4-aminophenyl)pyrrolidine-3-carbonitrile. NMR2: 1.48 (9H, s), 3.12-3.19 (2H, m), 6.46-6.50 (2H, m).
