(3R)-(+)-3-(tert-Butoxycarbonylamino)pyrrolidine → HCID 59556049, compound

Participants

Reaction Steps

The 4-hydroxy-4-pyridin-2-ylcyclohexyl methanesulfonate (0.245 g, 0.9 mmol) and tert-butyl (3R)-pyrrolidine-3-ylcarbamate (1.6 g, 8.59 mmol) were weighed into a microwave oven tube. The neat reaction mixture was placed into the microwave oven for 15 minutes at 71° C. The mixture was chromatographed on silica gel, eluting with 1% NH4OH in ethyl acetate/methanol (100/0 to 10/90), providing tert-butyl [(3R)-1-(4-hydroxy-4-pyridin-2-ylcyclohexyl)pyrrolidin-3-yl]carbamate. LC/MS: 362.2 (M+H, 100%). 1H NMR (CDCl3) δ 8.52 (m, 1H), 7.70 (m, 1H), 7.43 (d, 1H), 7.19 (m, 1H), 4.86 (bs, 2H), 4.20 (bs, 1H), 2.82 (m, 1H), 2.68 (s, 1H), 2.56 (m, 1H), 2.40 (m, 1H), 2.31 (s, 1H), 2.27-2.17 (m, 3H), 2.04-1.98 (m, 2H), 1.78-1.74 (m, 3H), 1.61 (m, 2H), 1.46 (s, 9H).
