Procedure:
HATU (440 mg, 1.16 mmol) was added to a solution of 6-fluoro-4-methyl-3-pyridinecarboxylic acid (supplied by Frontier Scientific) (150 mg, 0.97 mmol) in DMF (4 ml) and the mixture was treated with DIPEA (0.422 ml, 2.42 mmol). This mixture was stirred for ca. 10 min at ambient temperature. (3S)-3-Methyl-1-{[4-(trifluoromethyl)phenyl]sulfonyl}piperazine (may be prepared as described in Description 2) (358 mg, 1.16 mmol) was added and stirring was continued for 1.25 h. The reaction mixture was partitioned between DCM and saturated aqueous NaHCO3 solution (20 ml each). The layers were separated and the aqueous was washed with further DCM (2×20 ml). The combined organic layers were concentrated to leave a dark brown gum. Purification by silica chromatography (Biotage SP4, 25S cartridge), eluting with 12-100% ethyl acetate in hexanes, gave the title compound (432 mg) as a yellow gum.

Procedure:
A solution of 2 g of (RS)-2-(2-oxoethyl)-6-methoxy-1-indanone and 80 mg of p-toluenesulfonic acid in 70 ml of anhydrous toluene was heated on a water separator. A solution of 2.94 g of (R)-1-amino-2-propanol in 20 ml of anhydrous toluene was added dropwise to the boiling solution over a period of 5 minutes. Subsequently, the mixture was boiled for an additional 30 minutes, during which the solvent was reduced to a volume of 20 ml. The cooled reaction mixture was purified by column chromatography on silica gel (ethyl acetate/toluene 1:1). 1.5 g (63%) of (R)-1-(7-methoxy-1,4-dihydro-indeno[1,2-b]pyrrol-1-yl)-propan-2-ol were obtained as a solid with m.p. 75°.
