Reaction Steps
Borane (0.7 ml, 1M in tetrahydrofuran) was added to a solution of (3aR)-tetrahydro-1-methyl-3,3-diphenyl-3H-pyrrolo[1,2-c][1,3,2]oxazaborole (0.05 ml, 1M in toluene) in tetrahydrofuran (2 ml) at 0° C. A solution of the product from step (a) above (0.304 g) in tetrahydrofuran (3 ml) was added over 20 minutes and then stirred at 0° C. for 4hand at 20° C. for 14 h. Methanol was added and the solution was evaporated and the residue azeotroped with methanol. Purification by chromatography on silica eluting with petrol-ether gave the sub-title compound as a colourless oil (0.255 g).
