Reaction Steps
To a suspension of NaH (60% in mineral oil, 142 mg, 3.56 mmol) in DMF (2.00 mL) was added (1R,4S)-4-amino-1,2,3,4-tetrahydro-naphthalen-1-ol Intermediate A (145 mg, 0.88 mmol) and the reaction stirred for 20 min. A solution of Intermediate 58b (220 mg, 0.88 mmol) in DMF (2.00 mL) was added and the reaction heated to 60° C. for 1 h. The reaction was cooled and quenched by dropwise addition of methanol, before being diluted with methanol and loaded onto an SCX-2 cartridge, which was washed with MeOH. The product was eluted with 2M NH3 in MeOH; concentration in vacuo gave a residue. FCC, using 2-10% [2M NH3 in MeOH] in DCM, gave the title compound (145 mg, 44%). LCMS (Method 4): Rt 0.29 min, m/z 392.2 [MH+].
