HCID 5209072-Butanamine, 3,3-dimethyl-HCID 701495792-Isopropylsulfonyl-3-(3-methoxyphenylamino)-3-methylsulfanyl-2-propenenitrile

Product 1

HCID 701501352-Isopropylsulfonyl-3-(3-methoxyphenylamino)-3-(1,2,2-trimethylpropylamino)-2-propenenitrileYield 80%

Procedure

2-Isopropylsulfonyl-3-(3-methoxyphenylamino)-3-methylsulfanyl-2-propenenitrile (0.500 g, 1.53 mmol) was stirred in 2-amino-3,3-dimethylbutane (2 ml) for 48 h at 100° C. under nitrogen in a sealed flask. The reaction mixture was concentrated and the residue dissolved in dichloromethane,washed twice with 1N aqueous HCl, once with brine, and once with water. The organic phase was dried (sodium sulphate) and evaporated to afford 450 mg (80%) of the title compound as white crystals. Mp 59-62° C. 1H NMR (200 MHz, CDCl3): δ=0.84 (s, 9H), 0.96 (d, 3H), 1.40 (d, 6H), 3.00-3.33 (m, 2H), 3.82 (s, 3H), 6.64 (dd, 1H), 6.81 (dd, 1H), 7.31 (dd, 1H), 7.73-7.94 (m, 1H) 8.95 (br s, 1H).
