(2S)-3,3-dimethylbutan-2-amine → (S)-3-[3,5-Bis(trifluoromethyl)phenylamino]-2-(4-chlorophenylsulfonyl)-3-(1,2,2-trimethylpropylamino)-2-propenenitrile

Participants

Reaction Steps

3-(3,5-Bis(trifluoromethyl)phenylamino)-2-(4-chlorophenylsulfonyl)-3-methylsulfanyl-2-propenenitrile (0.200 g, 0.4 mmol) was stirred in (S)-1,2,2-trimethylpropylamine (0.2 ml) at 80° C. in a sealed flask for 20 h. Work up as described in Example 1, 2) gave 25 mg (11%) of the title compound as white crystals. 1H NMR (300 MHz, CDCl3): d=0.95 (s, 9H), 1.15 (d, 3H), 3.0 (m, 1H), 7.40 (s, 2H), 7.50 (d, 2H), 7.70 (s, 1H), 7.82 (d, 2H).
